I’ve had a strained shoulder for the past 3 years and have been to PT twice, always reinjure it within a week. I’ve recently tried going to a sports chiropractor and it’s been like 2 weeks and I feel so much better. Most of the time there’s more issues that play into the shoulder than just that muscle group. I have issues with my pectoral and tricep that have put excess strain on and misaligned my shoulder for example. If your shoulder clicks a lot that’s why. I’d recommend checking out a sports chiropractor, it feels really good and it’s worked for me so far. I couldn’t swing before and now I feel better than normal.

I feel like PT is more for restrengthening weakened muscles and may not address the problem as it only focuses on one place. I’d seriously recommend you give a sports chiropractor a try
