Can Fosamx D 70 mg be the cause of Ecchymosis Petechiae, I have developed what looks like an "under the skin" rash, on the ankles and upward on the leg, sometimes dark and also gets lighter, Doctor is doing blood work now, concerned about my platelets, it is possible there is no relation to Fosamax, but I am curious if anyone else has had this symptom. Thank you, dalecjim
