Fibromyalgia Repetitive Strain Injury
Symptoms may include, gradually increasing persistent pain or tenderness in the muscles or joints, tingling (pins and needles) or numbness in the hand or arm and a sense of loss of strength or sensation in the hand.

Back Pain
Patients suffering from back pain for longer than three consecutive months are typically diagnosed with chronic back pain. Symptoms include “shooting”, burning, aching, or “electrical” pain which is either localized or traveling through the lower extremities. Patients may experience numbness, stiffness, tingling, burning, or a pins-and-needles type sensation in the legs.

Mechanical back pain is a form of acute pain and is aggravated by movement and worsened by coughing. This type of pain is usually alleviated with rest. Mechanical back pain is typical of a herniated disc or stress fracture. For patients with this condition, forward movements of the spine usually cause pain. In addition, posture, coughing, sneezing, and movement can all influence pain coming from the spine.

Whiplash / After 6-8 weeks
The hallmark symptom of whiplash is neck pain which may present twenty-four hours following a trauma event. Symptoms of whiplash are: neck stiffness, neck muscle and ligament injuries; swelling and tenderness; delayed neck stiffness; delayed neck pain; ringing in the ears (tinnitus); headache; dizziness; abnormal sensations; burning; shoulder pain; back pain; memory loss; concentration impairment; nervousness; irritability; sleep disturbances; fatigue; and depression

Temporomandibular Joint Syndrome (TMJ)
Symptoms of TMJ include frequent headaches; popping, clicking, cracking or grating sounds while chewing; stuffiness, pressure or blockage in your ears; ringing or buzzing sound of the ears; frequent dizziness; tightness in the jaw and restricted mandibular movement; and sensitive teeth (especially to cold temperatures).

Post-Traumatic Headaches
The nature, extent, and duration of post-traumatic headache in part depends upon the degree of head trauma. Assuming that it is closed head trauma, the initial headache is usually related to the degree of head injury. Headaches that last more than two weeks would fall into the chronic post-traumatic headache classification.

There are three varieties of post-traumatic headache: (1) severe pain or circumscribed tenderness in a scar or site of impact and can persist for as long as six years following trauma; (2) a steady pressure sensation or aching pain in a circumscribed area or in a cap-like distribution; and (3) an episodic throbbing aching pain, usually unilateral and in the temporal or frontal region.

Post-traumatic headache is usually present every day. The large majority of patients experience a dull, aching, constant, generalized discomfort, with exacerbations that may be polar, generalized, or unilateral, and usually persist for several hours. At such times, the pain is usually throbbing in quality. The headache is commonly worsened by effort, stooping, coughing, or rapid head movement and is alleviated by reclining and/or sleep.

Depression
If you're depressed, you may notice mood changes, emotional changes, including inappropriate feelings of worthlessness or guilt. Many depressed people experience a marked lack of confidence and feelings of ineptitude. Some people will avoid situations that require any sort of responsibility for fear of failure.

Most of us know about the emotional symptoms of depression. But you may not know that depression can cause physical symptoms, too. Many people with depression feel pain or other physical symptoms which may include; headaches, back pain, muscle aches and joint pain, chest pain, digestive problems, exhaustion and fatigue, sleeping problems, sudden change in appetite or weight, dizziness or lightheadedness. Focused psychological therapy treatments can help alleviate these painful symptoms and can teach you ways to cope better with the pain.

Post-Traumatic Stress
When an individual experiences or witnesses a traumatic event or is confronted with an event that involves actual or threatened death or serious injury or otherwise triggers feelings of intense fear, helplessness, or horror, it is possible to persistently re-experience the traumatic event through recollections, flashbacks or dreams. Symptoms of post-traumatic stress include distress at exposure to internal or external cues that symbolize or resemble an aspect of the traumatic event, inability to recall an important aspect of the trauma, significantly diminished interest or participation in significant activities, feelings of detachment or estrangement from others, difficulty falling or staying asleep, irritability or outbursts of anger.
