Since March of 2007 I have been suffering from an unidentified rash.  It began the last weekend of March 2007 where my neck and my face was extremely red, puffy, and rashed out.  Since I am a life long allergy sufferer, my doctor prescribed Prednisone and it went away for a few weeks and then it was back.  This happened every month and a half and has been off and on ever since.  The method of treatment was always Predisone or a steriod shot and thus I have gained quite a bit of weight.  My allergist changed my allergy shots to see if that would help but I have just had to cut back my maintenance dose to be able to handle the shots.  This year the rash was not only on my face and neck but my ezcema has decided to be out of control as well so it covers my entire body and once again Prednisone.  When my face is red it is also very puffy and hot.  Does anyone have any ideas?  One note is that I have had some immense amounts of stress at work - don't know if there is a connection.  But I am afraid if I don't get this rashing and ezcema under control that my asthma will be affected.  Please help!
