Fosamax and d 70

recently developed under skin "rash",from ankle and upward on legs, my dr. is now doing blood work for ecchymosis petechiae, I am curious if anyone has this experience while using Fosamax D 70 mg. I am in good health and it is possible that this symptom is not at all related to Fosamax, which by the way I have stopped now for a while and probably won't go back. Stopped due to severe ache/pain in shoulder area and lower, so bad it was difficult to walk properly. Since stopping it I am walking straighter and no ache/pain. Even though my latest bone scan showed my osteopenia was better, I am off the drug on my own.

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
