Lymes Rash?

Does Lymes only cause the classic "bulls eye" rash?  Or can other rashes be part of lymes?  The reason I ask is because ever since I've been having sx I've had a strange rash on my belly just below my belly button.  It comes and goes and itches really bad.  I've been told that I may be having an allergy to my pants or belt.  But it is strange how it comes and goes.... I can wear something and get the rash and then wear it again and not have it.   It comes and goes every few months.  It may be totally unrelated to Lymes and other sx, but was just wondering.
  Thanks!

It does sound like a metal allergy to your jeans, but it is strange that it doesn't happen every time that you wear them.

My LLMD says he has seen about every kind of  rash with lyme disease.

I have often wondered if it doesn't cause me to become more sensitive to metals.  It seems that right now I break out from some necklaces that I been wearing for years without problem.
