I was on plaquenil and
biaxin for Lyme Disease for almost 4 weeks and just stopped taking them because I think it may have caused an allergic reaction. Last week I noticed some weird red spots on my buttocks on just one side. They looked like raised hives, but they weren't, they were flat and smooth. They didn't appear to have any dry skin on them, but I still thought it might be psoriasis, which I've never had before.
