As I write this, my right shoulder is on the painful side which varies in intensity as it has since I injured my right arm many decades ago throwing too many fastballs. That was another century well before advanced metrics and advanced orthopedic intervention. If the 17-year-old me today was faced with this I would scurry off to the shoulder specialist and undoubtedly have it repaired despite the fact my abilities were sub-standard.
A right of passage for far too many pitchers and even a growing number of position players is Tommy John Surgery. The procedure is used extensively from high school to seasoned professionals and for hurlers, the standard recovery is 18 months.
