When I was last deadlifting I heard 3 small snaps like when you break some string around the base of my neck and trap on the right side. I don't have pain when relaxed, but if I move my right arm across my body around chest height it begins to hurt. I am going to train my shoulders today and I hope I won't be impeded too much, but I am slightly worried as I have never done anything like this before. Also, when I tense my traps, the right side doesn't respond as well as the left until I focus more.
Does anyone have any idea what the problem could be? Did I just pull a muscle? Should I rest or power through it?
Thanks in advance
