Back pain is one of the most common reasons people go to the doctor or miss work, and is a leading cause of disability worldwide. It can range from a muscle aching to a shooting, burning or stabbing sensation. Back pain often develops without a cause that your doctor can identify with a test or an imaging study. Anyone can develop back pain, even children and teens.

Cervicogenic headache (CGH) occurs when pain is referred from a specific source in the neck up to the head. This pain is commonly a steady ache or dull feeling, but sometimes the pain intensity can worsen. CGH symptoms are usually side-locked, which means they occur on one side of the neck, head, and/or face.

A patient who has headaches as many days as not — at least 15 days per month — is said to have chronic daily headache (CDH). Not a specific type of headache, CDH is rather a descriptive term applied to any number of headache types. Headaches that can occur on a daily or near daily basis include Cluster,
Hemicrania continua, Idiopathic intracranial hypotension, Migraine and Tension headaches.

Complex Regional Pain Syndrome (CRPS) is a broad term describing excess and prolonged pain and inflammation that follows an injury to an arm or leg. CRPS has acute (recent, short-term) and chronic (lasting greater than six months) forms. CRPS used to be known as reflex sympathetic dystrophy (RSD) and causalgia. People with CRPS have changing combinations of spontaneous pain or excess pain that is much greater than normal following something as mild as a touch. Other symptoms include changes in skin color, temperature, and/or swelling on the arm or leg below the site of injury. Although CRPS improves over time, eventually going away in most people, the rare severe or prolonged cases are profoundly disabling.

Diabetic Neuropathic Pain (DNP) is characterized by tingling, burning, sharp, shooting, and lancinating or even as electric shock sensations. It is usually considered moderate to severe and often worse at night, causing sleeping disturbance. Exposure to high blood glucose levels over an extended period of time can cause diabetic peripheral neuropathy or damage to the nerves that go to the feet, legs and, when markedly advanced, to the hands and arms.

Fibromyalgia is a disorder characterized by widespread musculoskeletal pain accompanied by fatigue, sleep, memory and mood issues. Researchers believe that fibromyalgia amplifies painful sensations by affecting the way your brain and spinal cord process painful and nonpainful signals. While there is no cure for fibromyalgia, a variety of medications can help control symptoms. Exercise, relaxation and stress-reduction measures also may help.

Having neck pain alone is challenging enough, especially if it involves neck stiffness and reduced head mobility. When headache is also present, additional problems may include increased pain, visual disturbances, concentration issues, dizziness, or others. Getting an accurate diagnosis is important in order to create a treatment program to successfully manage the condition and reduce pain.

The different injuries resulting from a car accident can be as varied as the individual circumstances of each collision. Not all motor vehicle accident injuries are easily identified, but internal injuries can cause long-term and even chronic widespread pain.

A workplace injury can vary from something relatively minor, such as a small cut or bruise, to a fatal accident. According to the WSIB, the most common causes of workplace injuries are due to overexertion, slip and fall accidents due to debris or wet floors, falls from heights due to faulty equipment, getting entangled in a machine, repetitive motion injuries, hearing loss due to noisy environments and workplace violence.

Myofascial Pain syndrome is a chronic pain disorder. In this condition, pressure on sensitive points in your muscles (trigger points) causes pain in the muscle and sometimes in seemingly unrelated parts of your body. This is called referred pain.

Neuropathic pain is often described as a shooting or burning pain. It can go away on its own but is often chronic. Sometimes it is unrelenting and severe, and sometimes it comes and goes. It often is the result of nerve damage or a malfunctioning nervous system.

Shingles is a painful, blistering skin rash caused by a reactivation of the varicella-zoster virus. When the pain caused by shingles doesn’t go away after the rash and blisters clear up, the condition is called Postherpetic Neuralgia (Post-Shingles Neuropathic Pain). It occurs when a shingles outbreak damages the nerves. Common signs and symptoms of Postherpetic Neuralgia include
severe pain that continues for more than 1 to 3 months in the same place that the shingles occurred, even after the rash goes away burning sensation on the skin, even from the slightest pressure sensitivity to touch or temperature changes.

Post-Surgical Pain is defined as pain lasting more than 3 to 6 months after surgery. The pain differs in quality and location from pain experienced prior to surgery, and is usually associated with iatrogenic neuropathic pain caused by surgical injury to a major peripheral nerve.

The shoulder has a wide and versatile range of motion. When something goes wrong with your shoulder, it hampers your ability to move freely and can cause a great deal of pain and discomfort. The most common cause of right shoulder and arm pain is an issue with your rotator cuff, such as tendinitis or bursitis. Other potential causes include fractures, arthritis, and cervical radiculopathy.

Sports injuries are commonly caused by overuse, direct impact, or the application of force that is greater than the body part can structurally withstand. Common injuries include bruises, sprains, strains, joint injuries and nose bleeds. Different sports injuries produce different symptoms and complications.

Trigeminal Neuralgia is a condition characterized by pain coming from the trigeminal nerve, which starts near the top of the ear and splits in three, toward the eye, cheek and jaw. We have two trigeminal nerves for each side of our face, but trigeminal neuralgia pain most commonly affects only one side. The main symptom of trigeminal neuralgia is sudden attacks of severe, sharp, shooting facial pain that last from a few seconds to about 2 minutes. The pain is often described as excruciating, like an electric shock. The attacks can be so severe that you're unable to do anything while they're happening.

Whiplash is a neck injury due to forceful, rapid back-and-forth movement of the neck, like the cracking of a whip. Whiplash is commonly caused by rear-end car accidents. But whiplash can also result from sports accidents, physical abuse and other types of traumas, such as a fall. The long-term effects of whiplash can include chronic pain and stiffness in the neck and shoulders, ongoing bouts of dizziness, ringing in the ears that is constant or comes and goes.
