I Was Prescribed Aggrenox For Several Years Following A Suspected

I was prescribed Aggrenox for several years following a suspected but unconfirmed TIA. No problems and well reimbursed while working. Then I retired and switched to Clopidogrel 75mg, as reimbursement coverage options for Aggrenox were so poor. After 60-days on Clopidogrel, I am experiencing increasing joint pain, particularly in the elbows, and to a lesser extent in the shoulders. Suggestions?
