Good news - Ortho agrees that there's no tendon/ligament/muscle issues. All looks solid. Also, he dismissed the bone growth being a factor. Said his arms are done growing. So not worried about growth plate issue.
Bad news - He can't find the exact cause. Concerned there may be a hairline stress fracture that he can't see, as SOMETHING has to be causing the joint effusion. So prescription is no overhand throwing OR hitting for 5 more weeks (July 20th). Which means 17U summer is gone in terms of games/tourneys.
Next step is a day of mourning, then sort out what he can continue doing for the next 5 weeks. So far we have:
- Study for second SAT
- Lift/run
- Catch pens
- One arm hitting
- WIN Reality
