I have been experiencing pain in my right shoulder while doing two key movements for he past 3 weeks; upright rows, and flat bench. It's bad enough that I can perform either at anywhere close to 85% 1RM - more like 30%. The funny thing is that I don't have any discomfort while doing everything else; shoulder press, incline, decline, dips, etc., you get the picture. Anyway, was wondering if anyone else has experinced anything like this before and what it might be? What advise do you have?

BTW, it has been 4 weeks since my last injection and the pain has been coming on increasingly each week. Could it be realated?
