Gout (also referred to as gouty arthritis) is a debilitating form of arthritis caused by the accumulation of uric acid crystals in the joints and tendons. It is an intensely painful disease that results from an increased uric acid concentration in the bloodstream. The most frequent location of symptoms is the 1st toe (75% of initial attacks), although it can also affect many other joints such as the ankle, knee, digits, and spine.
The patella, commonly referred to as the "knee cap", and its tendon transmit power from the quadriceps to the lower leg. Normally, as the knee bends, the patella slides smoothly along a groove in the thigh bone. However, under certain conditions the patella may experience forces which push it against the sides of the groove, causing pain.
Post-traumatic headaches can begin after a car accident. Frequently, post-traumatic headaches are painful and quite debilitating. They can start immediately after a collision or within hours or days.
