My son is Class of 2014 LHP/OF. He suffered mild labrum strain / bursitis flare in early April, took cortisone shot and does regular strengthening with 5 lb. weight. He started throwing program a couple of weeks ago and is now playing OF. He started throwing bullpen last week and is pain free, but a little sore the day after. He feels like his velocity is very low during bullpen.
Any insight into how long it typically takes for pitcher to gain full strength after minor inflammation in shoulder?
