Back pain is one of the leading reasons for doctor visits and lost days from work. Each year, nearly $1 billion dollars are spent on treating back pain, lost wages, litigation, and disability in this country.
Neck pain is a leading cause of pain in the aging population, as well as subsequent to auto accident-whiplash type injury, in which the neck is violently snapped back, then forward, after the victim is usually hit from behind, by another vehicle.
Knee pain is a common reason that people visit their doctors' offices or the emergency room. Often, knee pain is the result of an injury, such as a ruptured ligament or torn cartilage. However, some medical conditions can also cause knee pain, including arthritis, gout and infections.
Spinal stenosis is a narrowing of one or more areas in your spine — most often in your upper or lower back. This narrowing can put pressure on the spinal cord or on the nerves that branch out from the compressed areas. This can lead to a number of problems, depending on which nerves are affected. In general, spinal stenosis can cause cramping, pain or numbness in your legs, back, neck, shoulders or arms; a loss of sensation in your extremities; and problems with bladder or bowel function.
Reflex sympathetic dystrophy (RSD), also known as complex regional pain syndrome (CRPS), is a chronic, painful, and progressive neurological condition that affects skin, muscles, joints, and bones. The syndrome usually develops in an injured limb, such as a broken leg, or following surgery. Many cases of RSD involve only a minor injury, such as a sprain. In some cases, no precipitating event can be identified.
The shoulder is the most mobile joint in the human body. The joint includes four tendons. The purpose of a tendon is to hold muscle to bone. Together, these four "rotator cuff" tendons stabilize the upper arm bone to the shoulder socket and allow a wide range of motion in the shoulder.
The longest nerve in your body is the the sciatic nerve. It runs from your pelvis through your buttock and hip area and down the back of each leg. It controls many of the muscles in your lower legs and provides feeling to your thighs, legs and feet. The term "sciatica" refers to pain that radiates along the path of the sciatic nerve — from your back into your buttock and down the leg.
