I brought this up a while ago but it's still troubling me. When I do cardio (running or bag work) I get a sharp but dull (if that makes sense) in my right shoulder. Sometimes I'll feel it about 10 minutes after a session but sometimes (rarely) it'll start whilst im excercising and it's incredibly dehabilitating. It's no so much the pain but the sensation (it's like having a huge weight IN my shoulder) that fucks with me. To boot, my hand shakes after. Not alot, but sort of enough to notice it. Like right now, as I'm typing it feels feint(sp) as I type. I can lift fine. I do proper sets of lifting and for longer periods of time and I wont get a peep out of it. It does shake after but as does my whole body as it's recovering. My shoulder and hand only play up when I do cardio. I was on the bag for an hour at 1pm and it's now 8pm and my hand is still slightly shaking. Anyone else get it or know what Im talking about?
