I have an issue with my shoulder which occurred six months ago because I crashed quite badly while skiing. The first month I couldn’t raise my arm above my head because it would hurt. It's got a lot better in terms of ROM but there is still some noticeable difference between my two arms when raising them above my head, no pain, just some discomfort in my scapula. Around 4 months after though I did start to feel pain in my shoulder. Now my shoulder is the real problem with the scapula still feeling some discomfort.
Just over a week ago it really started to hurt quite a bit. But it's the first time that my shoulder had a problem with sPL/PE1. Should note that the pain has only been initiated outside of training. The pressure I can now feel on my shoulder and it hurts. My main concern is with sPL training as I can't perform the exercise at the moment without pain. What can I do as a temporary substitute until my shoulder becomes capable again?
Also with regards to F1 and H1 training in general, doing above the head shoulder placement either hurts or creates discomfort (either the PE or iM). So for a lot of exercises and mobility I have now decided to change arm placement (such as MN/PE1 having arms stretch out sideways), reduce or remove the weight being used or in terms of H1, regress, as I can't perform the PE2>iM properly. My arm of my good shoulder pulls my arm of the bad shoulder effectively making my arms wonky as they are pulled to a side with respect to my body (I can't do the iM symmetrically behind my body.)
Should I just continue like this, compensating and not forcing ROM? Overall, what would be the best course of action to take to fix my shoulder? And most importantly so as to not stop sPL training, what substitute exercise or mobility/rehab can I do for my scapula/shoulder?
