Sports injuries are injuries that occur in athletic activities. Some sports injuries result from accidents; others are due to poor training practices, improper equipment, lack of conditioning, or insufficient warm up and stretching. Many sports injuries can be due to overuse of a part of the body when participating in an activity. Other types of injuries can be caused by hard contact with something. Sports injuries typically involve the musculoskeletal system, which includes the muscles, bones, and associated tissues like cartilage.
Osteoarthritis, sometimes called degenerative joint disease, is the most common form of arthritis. Osteoarthritis occurs when cartilage in the joints wears down over time. The smooth surface of the cartilage becomes rough, causing irritation. Eventually, if the cartilage wears down completely, there may be no cushion left between the bones and the joint may be left with bone rubbing on bone, causing damage to the ends of the bones and the joints to become painful.
The sciatic nerve is the longest nerve in your body, running from the spinal cord to the buttock and hip area and down the back of each leg, and about the size of your little finger. Sciatica is a condition where the sciatic nerve is irritated. The most telltale symptom of sciatica is pain that radiates along the path of the sciatic nerve- from the lumbar area to the buttock and down the back of the leg. The pain can be anywhere from a mild ache to a severe sharp or burning pain, numbness or weak muscles along the nerve pathway, and tingling or pins and needles feeling in the toes or foot.
