The pectoralis major or “pecs” is commonly thought of as the chest muscle. It originates on the clavicle, sternum, costal cartilage , and the external oblique aponeurosis. It inserts on the intertubercular groove of the humerus. Its main actions are to adduct the shoulder and to internally rotate the humerus. This muscle gets chronically shortened by a rounded shoulder forward posture such as from prolonged sitting. Tightness in this muscle can cause strain in the rhomboids and traps. When trigger points form in this muscle they refer pain into the anterior shoulder, as well as the anterior chest and medial aspect of the arm. Trigger points in the pecs can also cause nipple hypersensitivity. Trigger points in the left pec muscle can mimic heart pain.

Pain
Why am I so dizzy after my whiplash?
Whiplash, or better termed “Whiplash Associated Disorders” (WAD), is a condition that carries multiple signs and symptoms ranging from neck pain and stiffness to headache, confusion, ringing in the ears, and more. But can WAD cause dizziness? Let’s take a look!
Dizziness is a general term that is used rather loosely by the general population. We’ve all experienced dizziness from time-to-time that is considered “normal,” such as standing up too quickly or while experiencing a rough flight.
Often, dizziness and problems with balance go hand in hand. There are three main organs that control our balance: 1) the vestibular system (the inner ear); 2) the cerebellum (lies in the back of the head); and, 3) the dorsal columns (located in the back part of the spinal cord). In this article, we will primarily focus on the inner ear because, of the three, it’s unique for causing dizziness. Our vision also plays an important role in maintaining balance, as we tend to lose our balance much faster when we close our eyes.
It’s appropriate to first discuss the transient, usually short episode of “normal” lightheadedness associated with rising quickly. This is typically caused by a momentary drop in blood pressure, and hence, oxygen simply doesn’t reach the brain quick enough when moving from sitting to standing. Again, this is normal and termed “orthostatic hypotension” (OH).
However, OH can be exaggerated by colds, the flu, allergy flair-ups, when hyperventilating, or at times of increased stress or anxiety. OH is also associated with the use of tobacco, alcohol, and/or some medications. Bleeding can represent a more serious cause of OH such as with bleeding ulcers or some types of colitis, and less seriously, with menstruation.
The term BPPV or benign paroxysmal positional vertigo, has to do with the inner ear where our semicircular canals are located. The canals lie in three planes and give us a 3D, 360º perspective about where we are in space. The fluid flowing through these canals bends little hair-like projections, which are connected to sensory nerves that tell the brain about our spatial position. If the function of these canals is disturbed, it can mix-up the messages the brain receives, thus resulting in dizziness. Exercises are available on the Internet that can help with BPPV (look for Epley’s and Brandt-Daroff exercises).
DANGEROUS causes of dizziness include: HEART – fainting (passing out) accompanied by chest pain, shortness of breath, nausea, pain or pressure in the back, neck, jaw, upper belly, or in one or both arms, sudden weakness, and/or a fast or irregular heartbeat.
STROKE – sudden numbness, paralysis, or weakness in the face, arm, or leg, especially if only on one side of the body; drooling, slurred speech, short “black outs,” sudden visual changes, confusion/difficulty speaking, and/or a sudden and severe, “out of the ordinary” headache. CALL 911 (or the number for emergency services if you’re outside the Canada) if you suspect you may be having a heart attack or stroke!
Lumbar Spine Stabilization

This is a great way to increase the stability of your lower back.
- Lie with your stomach over a therapeutic ball while stabilizing yourself with your feet and arms and keep your head in line with your body.
- Tighten your abdominal muscles to flatten the spine by pulling your belly button towards your back and hold the contraction throughout the exercise.
- Bend one knee and lift it up towards the ceiling.
- Lower the leg and repeat on the other side.
Trigger points in the rhomboid muscles.
This is another common muscle to get trigger points. It originates on the spinous processes of the T2-T5 vertebrae. It inserts on the medial border of the scapula. It’s main actions are to adduct the scapula pulling it back toward the spine, and to rotate the glenohumeral joint downward. This muscle also prevents wining of the scapula. This muscle is often overloaded by a sitting posture where the shoulders are rolled forward such as when using a computer. The Rhomboids are often weak and under trained in people. Trigger points in this muscle cause pain and ache in the upper back between the shoulder blade. Strength trading for this muscle is necessary to help prevent postural overload. 
When Are My Shoes “Done”?

Running shoes need to be replaced every 250 miles. There are three basic options:
✓ Motion Control Shoes – Designed for people with low or no arches, these shoes are for runners who strike the ground on the outer edge of their foot. Avoid overly stiff shoes as these decrease you perception of ground strike and lead to new injuries.
✓ Stability or Neutral Shoes – Designed for people with normal or average arches and running mechanics. The shoe contains some cushioning to absorb shock and prevent injuries and some rigidity to avoid pronation.
✓ Cushioned Shoes – Designed for people with high arched feet. Their footprint will typically leave a thin band along the foot’s edge. As they run weight is distributed from heel strike to the outer edge of the foot and small toes that bear the brunt of “lift off.” This shoe is more flexible and absorbs the shock created by the lack or rotation (under-pronation) created by their running style.
Trigger points in the trapezius muscle.
The trapezius muscle is a large diamond shaped muscle in you mid/upper back and neck. This muscle is one of the most common sites where trigger points can form. This muscle originates on the Nuchal ligament and the spinous processes of C6-T12. It inserts on the spine of the scapula, the acromion process, and the distal clavicle. The upper fibres elevate the shoulder and rotate the glenoid fossa (shoulder socket) upward. The lower fibres assist this motion as well as help depress the shoulder. The middle fibres of this muscle strongly adduct the scapula. This muscle is susceptible to postural overload such as sitting at desk all day. Trigger points on the lateral upper edge refer into the lateral neck and temples, causing “tension neck ache”as well as headache pain.Trigger points in the middle and lower fibres refer pain into the posterior neck and shoulder. 
How long does Whiplash last?
First, what is whiplash? It’s a lot of things, which is why the term WAD or Whiplash Associated Disorders has become the most common term for the main signs and symptoms associated with a whiplash injury. WAD is usually associated with a motor vehicle collision, but sports injuries, diving accidents, and falls are other common ways to sustain a WAD injury.
To answer the question of the month, in most cases, the recovery rate is high and favors those who resume their normal daily activities. The worse thing you can do when you sustain a WAD injury is to not do anything! Too much rest and inactivity leads to long-term disability. Of course, this must be balanced with the degree of injury, but even when the injury requires some “down time,” stay as active as possible during the healing phase.
Many people recover within a few days or weeks while a smaller percentage require months and about 10% may only partially recover. So what can be done to give you the best possible chance to fully recover as soon as possible?
During recovery, you can expect your condition to fluctuate in intensity so “listen” to your body, let it “guide” you during activity and exercise, and stay within “a reasonable boundary of pain” during your activity. Remember, your best chance for full recovery FAVORS continuing a normal lifestyle. Make reasonable modifications so you can work, socialize, and do your “normal” activities!
The KEY: Stay in control of your condition – DO NOT let it control you! Here are some tips:
1) POSTURE CONTROL: Keep the weight of the head back by gliding your chin back until you “hit” a firm end-point. Then release it slightly so it’s comfortable—this is your NEW head position!
2) FLEXIBILITY: Try this range of motion (ROM) exercise… Slowly flex your neck forwards and then backwards, then bend your neck to the left and then the right, and then rotate it to the left and to then to the right. THINK about each motion and avoid sharp, knife-like pain; a “good-hurt” is okay! Next, do the same thing with light (one-finger) resistance in BOTH directions. Try three slow reps four to six times a day!
3) MUSCLE STRENGTH: Try pushing your head gently into your hand in the six directions listed above to provide a little resistance. Next, reach back with both hands or wrap a towel around your neck and pull forwards on the towel while you push the middle of your neck backwards into the towel doing the chin-tuck/glide maneuver (same as #1). Repeat three to five times slowly pushing, and more importantly, release the push slower! This is the MOST IMPORTANT of the strengthening exercises in most cases! Next, “squeeze” your shoulder blades together followed by spreading them as far apart as possible (repeat three to five times).
4) PERIODIC BREAKS: Set a timer to remind yourself to do a stretch, get up and move, to tuck your chin inwards (#1) and do some of #2 and #3 every 30-60 minutes.
5) LIFTING/CARRYING/WORK: Be SMART! Do not re-injure yourself. Change the way you handle yourself in your job, in the house, and while performing recreational activities.
6) HOUSEHOLD ACTIVITIES: Use a dolly to move boxes and keep commonly used items within easy reach (not too high or low).
My back hurts, why look at my feet?

Improperly supported feet can affect the alignment of all of the structures above. To improve your overall comfort:
✓ Choose shoes with good arch support.
✓ Avoid going barefoot or wearing shoes that lack support (i.e. flip-flops). The following brands of sandals provide better than average arch support: Naot, Fit Flops, Orthoheels, Abeo, Vionic and Yellow box.
✓ Avoid high-heeled shoes or boots (keep heels to a maximum of 1½ inches, especially if you are going to be doing a lot of walking).
✓ “Cross-trainer” athletic shoes tend to provide the best all around support and shock absorption for daily activities.
✓ Patients with fallen arches should consider adding arch supports or orthotics.
✓ Repair or replace shoes with worn soles or heels.
Why do so many suffer with CTS?
According to the literature, carpal Tunnel Syndrome (CTS) is one of the most prevalent upper extremity complaints. In fact, it IS the most common “compression neuropathy” (of which there are many) and affects 3-6% of adults in the general population. Additionally, CTS can affect BOTH hands in up to 50% of patients with the condition!
The CAUSE of CTS is often unknown and typically comes on gradually, making it difficult to determine a definite cause or specific “date of onset” for CTS.
Symptoms such as numbness, tingling, loss of dexterity, loss of strength (like pinch or grip), and the need to shake the hand or flick the fingers to restore sensation are ALL VERY COMMON CTS SYMPTOMS. The REASON for these symptoms boils down to one thing: The median nerve in the wrist gets pinched! The cause/s can include:
1) Repetitive motion from either work or hobbies like assembly line work or playing a musical instrument can cause swelling within the carpal tunnel, placing extra pressure on the median nerve as it passes through.
2) Obesity can contribute to CTS due to extra fluids or fatty deposits that can build up within the carpal tunnel.
3) Pregnancy: Elevated levels of the hormones estrogen and progesterone can cause the body to retain fluids and increase pressure in the carpal tunnel.
4) Arthritis: Osteoarthritis can lead to CTS (such as when a spur forms inside the tunnel). Rheumatoid arthritis can lead to an autoimmune response and antibodies that end up attacking the cartilage of the joints in the wrist, which can lead to CTS.
5) Hormone-related conditions: In diabetes mellitus, the blood becomes thicker due to high sugar levels (like syrup) and can’t pass through the small blood vessels, resulting in “neuropathy,” which can make CTS more likely. In hypothyroid, low thyroid function results in “myxedema,” a specific type of swelling that makes CTS more likely to occur.
6) Trauma: A wrist fracture could cause the carpal tunnel to “collapse” or change in shape resulting in less space for the nerve to travel through.
7) Mass lesions: A “ganglionic cyst” is a good example. This is where joint fluid leaks out and forms a “bump” on the INSIDE the carpal tunnel, which reduces space and increases pressure in this anatomical structure.
8) Amyloidosis: This is a rare condition where a protein substance called “amyloid” builds up in any tissue or organ. If this occurs in the wrist, it can “pinch” the median nerve as it passes through.
9) Sarcoidosis: This is the growth of small collections of inflammatory cells called “granulomas,” which can accumulate in different parts of the body. If it occurs in the wrist, pinching can occur.
10) Multiple Myeloma: This is a type of cancer that affects the bone marrow, and inflammation in the wrist can occur creating the pressure increase on the median nerve that can lead to CTS.
11) Leukemia: This too is a type of cancer that involves the white blood cells, and CTS can result from its effects on the tissues in the wrist.
12) Anatomy: The size and shape of the carpal tunnel is hereditary, and some of us have a smaller tunnel than others. If CTS is present in multiple family members, this “genetic” factor may play a role.
There are other conditions that can “mimic” CTS, but doctors of chiropractic are trained to perform an accurate history and examination so treatment can be directed in the proper manner!
Trigger points in the Levator scapula
The Levator scapula is a muscle in your neck that originates on the transverse processes of C1-C4 and inserts on the superior part of the medial border of the scapula. The primary actions of this muscle are to elevate the scapula and rotate the glenoid fossa downward. It also rotates the neck to the same side and assists in extension. When this muscle is tight it restricts neck rotation resulting in the classic “stiff neck”. With a forward head position the Levator is often stretched and over worked. To help combat this you must get the head back by releasing the anterior chest and neck muscles. Trigger points in this muscle refer pain into the angle of the neck and down the shoulder blade.
