I am just doing some research. I have been on medication for 15 years Imuran and I have been feeling rather poorly. My dr. wants me to get labs done. I was just looking to see more about this drug.????I noticed extreme petechiae on my lower ext. this morning, and several bruises I have no idea where no got them from, unusual wt. loss, unusual tiredness more so then normal, persistent sore throat/bronchitis, abd. pain/swollen. Chest pain swollen glands. I a little scared as I have s/s of Bone marrow suppression.?? I think I will just need t sleep on this. I have no one to really confide in. Dr. is this a precursor to thrombocytopenia or lymphoma. I have a hx. of breast CA. I have Crohn s Disease. I have been on 100 mg up 200 mg of Imuran over the course of 15 years. I have been feeling poorly for a month or so now. can you help me figure this out????Are you there Dr.??????
