I am a 56 yr old white female who has sufered for the past several years with pain in shoulders, arms, hips, knees and lower back. I develop a rash on my left arm that appears to be tiny blisters but does form a ring and has severe itching and at these times seem to have more pain. I have had two vervical fusions in the past. I did suffer a tick bite in 2006 and had the bull's eye rash but tests for lymes was negative. I continue to become worse where now I am unable to walk but short distances and have severe pain in my lower back and legs, extreme weakness and fatique. I am afraid that I may have lyme disease but my PCP will not test me again and just brushes my symptoms off. What type of provider can I see that can answer my questions, a neurologists, arthritis, autoimmune?
