This afternoon I ended up going back to the clinic which first treated my sinus infection then saw the rash a week ago.
The doc assured me it was not sjs. Because of the rash (not sure if I'd call them lesions however I am not familiar with exactly what that means. They are red pimply raised small dots) ... anyway he gave me a shot of cortisone and gave me a one week (or 5 days?) prednisone pack ... I hate taking prednisone but he said it should calm the rash. I have taken prednisone in the past for polymyositis for 3 years.
Also I have read on the web that usually the rashes come right back after you stop the prednisone. He said not necessarily so. So much conflicting information.

Anyway I convinced him to give me another round of antibiotics, this time Biaxin, which I have always taken in the past.
I wanted to ask about the possibility of mono but forgot. Darn!
Thanks again for the quick reply.

If such signs or symptoms are present, the patient should be evaluated immediately. LAMICTAL should be discontinued if an alternative etiology for the signs or symptoms cannot be established.
Prior to initiation of treatment with LAMICTAL, the patient should be instructed that a rash
