Repetitive throwing can irritate, inflame or strain the flexor and pronator tendons in the forearm -- the ones that bend the wrist toward the palm -- where they attach to the medial epicondyle, which is the bony bump on the inside of the elbow that is actually the base of the humerus bone. Flexor tendinitis, also known as medial epicondylitis, can manifest as pain on the inside of the elbow, loss of range of motion or a popping or locking sensation.
Typical recovery time
A wide range of timetables exists for flexor tendon injuries. Depending on the severity, they can carry a recovery time of anywhere from 1-2 weeks to 1-2 months. If surgery is required, recovery can take upwards of six months.
