it was a physician at UK sports medicine. He Didn't seem too concerned. Son has just come off rehab for another elbow issue, PT cleared him to throw. Doctor said he could work back into throwing. Got one elbow thing corrected and this popped up. Doctor says a nerve issue. We've been doing some stretches for the nerve in the area of elbow, stopped the planks, trying to keep him from leaning on elbows. Supposed to go back to him in a few weeks, I think we're gonna see another physician for second opinion
