Hi guys I need some advice. I was going to my gym and lifting pretty light weights, and using machines etc. In addition I was also learning Krav Maga. I noticed at one stage (no specific time) that when I did this one stretch, which is where you bring your elbow up behind your head and press your elbow down with your other hand, that my area around my shoulder (and what I think is my rotator cuff) is hurting a bit. This has been going on now for about 2 months. I have not done any krav maga or gym since (due to time constraints) but I still have this dull and slight pain when I lift my right arm up and across my body. Could I have damaged something? And what is the best course of action to heal the injury? This is very important to me as I am also a violinist and I don't want problems with my arms when I am older. Thanks in advance! PS Sorry if this is maybe the wrong forum to post this in. I couldn't find a more suitable place.
