I am 56 years old male, 138 lb, 5-6. it is exactly 2 years that i take 75mg plavix, toporol xl25, lipitor 40mg, due to stint at lad. it has been 3 weeks that i am experiencing ringin in ears (hissing sound). I went to ent specialist, no infection, no hear loss, no founding. my question is could this be the side effect of one or more of the above medicine?
