Whats causing my joint pain?

[Lucasta]

For the past 2 weeks my joints have been screaming bloody murder. Wrists, elbows, shoulders, and now my knees and even my damn back. Im just coming off a test c cycle and pct begins this weekend. I have my pct stuff lined out already. Ive been taking forma at 5pumps twice a day for the past 5 weeks with no noticeable ill effects, I have exemestane on hand have taken it at 12.5 mgs a few times but wasnt sure if that was causing my pain or not. All i know is this shit hurts to the point to where it makes it hard to lift and hell just hard to do everyday things. I take 3grams of fishoil and a glucosamine/chondriotin/msm supplement everyday. Is the forma knocking out too much estrogen or what? Any ideas guys?
