it could be alot orf different things,thats why some testing really does need to be done here in order to better pinpoint the area/s of affectation. getting MRIs done on mostly that shoulder but also possibily the c spine area really would help here to either rule in or rule out certain types of problems that can give you the ongoing symptoms you have described. you do have to start somewhere ya know? this could simply be a nerve impingement within that shoulder itself somewhere,or something a bit more in depth, but by not actually giving that whole area a really good in depth look,you really wont know a whole lot. while any good physio can run you thru ROMS,it wont be able to detect something like a partial tear in any of the tendons within that rotator cuff area. as long as there is indeed some level of attachment,your ROMS could still may be okay/normal, but any partial tear will eventually progress to a complete if not interveined upon at the earlier stages. this is what happened to me last year. and if i had just gotten my MRI when the pain started to really become much worse,that final snap would not have occured out of the blue one morning while simply lifting my purse off the top of my fridge that morning, it just decided that was enough and completly snapped on me. the earlier you can catch a partial the much easier it is to fix and also the post op pain and rehab is no where near what you have to deal with from a complete tear. i wish i had known earlier now. any other symptoms besides what you described here already? does this just stop at your elbow or are fingers being involved in some way too? does that area within your shoulder actually "feel' somewhat 'cramped up' in some way?
but we are getting way ahead of ourselves here. just try like all heck to obtain that MRI just to really 'see' what is possible to see in there with MRI. that would dictate your next steps much better than merely 'guessing' as to what is going on in there right now,ya know? tell your physio that you would feel a whole lot bettter just knowing what that root casue actually is by MRI than hoping it isn't something worse which in some cases,certain types of PT could actually make things alot worse for you in the long run. better safe than sorry here, when there is a way to really look into that shoulder,it should be a no brainer for most docs to simply 'do' for you,but for some reason,they prefer to still "guess' and hope they are right. i would push for that MRI rihgt now just so YOU know whats going on and your physio too. this would help with setting up a real good appropriate plan of action than hoping he is guessing right. i do hope this is simply an impinged nerve that can be corrected with the right therepies( i am actually dealing with the impingment crap myself as we speak right now). please keep me posted as to what you find out,K?
