A good sports physical therapist would be my first stop. Mechanical issues at the elbow can irritate and entrap the nerves at the elbow. The poor old elbow will get beat up because of mechanical issues above and below the elbow. It isn't as simple as an "elbow injury" typically. The difference between a good sports physical therapist and a good orthopod, is that the orthopod will typically focus on the elbow only (which is his/her job) and focus on the "symptomatic" area (which is a needed assessment). A good sports physical therapist will not only look at the elbow, but will look above the elbow (shoulder, scapula, spine) and below the elbow (forearm, wrist) and look for the "cause" of the elbow malfunction. He/she will look for normals not only at the elbow, but above and below, will watch him move, look for abnormal movement patterns, postures, weaknesses, imbalances, etc. A lot of times the ortho is not needed at first. If just depends on what you are comfortable with, what your insurance dictates, and your state rules and regulations are regarding physical therapy and direct access. When an ortho is needed, it typically means that good conservative, non-surgical methods of care did not work. I would hope that at 14 y/o, good, conservative, hands-on sports physical therapy care would correct the problem. Good luck!
