Biaxin and blisters

I'm on my third day of Biaxin XL 500MG and I have small red bumps on my hands and the bottoms of my feet. They hurt like blisters. The back of my throat has tiny red dots all over. It doesn't sound like the same simptoms as everyone else.

I had a really bad bleeding ulcer on 06-02-04 and was in the hospital 4 days. One month later I had to see a GI doctor. He told me that I had the bacteria that causes ulcers. I was given a Prevpac that consist of Previcid 60mg 2x a day, Amoxicillin 1000mg 2x a day, and Biaxin 500mg 2x a day. By the second dose I was nervous, sweating, panicking, and a taste like metal in my mouth. I told the doctor about it and he said I was just under a lot of stress. He said to keep taking the meds. Two days later I had the first panic attack of my life. As the days past the symptoms got worse and I got blisters on my tounge. I changed doctors and was told by 2 different ones that the Biaxin was the culprit. That was 16 months ago and I still have a metalic taste once in a while, nervous tremors, blisters on my tounge about once a month, depression once in a while,and i'm scared to try any other meds to help my current symptoms.
