I was diagnosed 1 month ago after a platelet count of 7. I've been on 75mg of Prednisone for the past month and my count as of 2 days ago was 172. My hematologist has started me on the weaning off process so starting yesterday I am now on 30 mg of Prednisone for the next month, then 25 for the following month and so on. I am pleasantly surprised that have not really experienced any harsh side effects of Prenisone. I was expecting a moonface, ravenous hunger, weight gain, but none of that has happened. However, I am extremely tired and the only other thing I am experiencing is a tightness in my chest. This tightness started about a week after starting Prednisone. Is this a side effect others have experienced? Or should I be more concerned that it is something else?
