question: I have Hashimotos's Thyroiditis and my platelet count has dropped to 11,000.  I take no other medications except synthroid and lisinopril for HBP.  My doctor can find no reason for my platelet drop. He say it is idiopathic.  I have been on a high dose of steriods which brought them up to normal for a short time, but they dropped again.  Now I'm back on the steriods for a while.  My last TSH was 46, and I cannot help but think something is going on between the two of these conditions.  My TSH has never been this high and I have had Hashimotos since I was 12 and I'm 40 now.  Please Help!  This has only been going on for 2 months and I do not want to and am not ready to give up my spleen yet.
