In reply to Reach>Talent:
I've knacked both of my shoulders in the last 8 months.
Left one was diagnosed as Supraspinitis (sp.). It hurt when being used, but not when resting. 2-3 months of physio fixed it.
Right one has just been diagnosed as impingement. Hurt all of the time and can't lift the arm above shoulder height without pain. Just started getting physio for it and it's showing an improvement already. However, if physio doesn't fix it, it will need something more drastic (cortisone/operation).
Physio keeps telling me to rest, but gentle climbing doesn't seem to make it any worse. I'm sticking to the physio routine very carefully though.
Go see the doctor and get a referral so that an expert can sort you out.
