could someone tell me what this is, i though it could be atheritis but im only 18 so i don`t know if it is

Answers:

it could be a muscle spasm. Spasms may occur when a muscle is overused and tired, particularly if it is overstretched or if it has been held in the same position for a prolonged period of time. In effect, the muscle cell runs out of energy and fluid and becomes hyper excitable and then develops a forceful contraction. This spasm may involve part of a muscle, the whole muscle, or even adjacent muscles.
