Had a shoulder re-alignment done over the Xmas break, my sister is an athletic therapist and osteopath and she's been treating me since my shoulder separation in May. Turns out I have overdone my shoulder and chest, and my muscles are causing my bones and joints up and forward more than they should be. Almost like a forced slouch that I can't see even when standing up straight with my shoulders back. So even though my back is decent I really need to build some lats to help pull everything back into alignment. She said my upper and lower traps were way overbuilt. I think she's just mirin'
But, just goes to show that balance in your workout is important. There can be a lot going on beneath the surface that you don't realize. I would encourage everyone here that's really into training, especially the heavy lifters, to get yourself checked out by a physio or the like once in a while just to keep informed of what's going on with your bones and joints. Would hate to see anyone end up with some problems down the line that could be easily preventable
