Suggest Remedy To Get Rid Of Rash On Skin

Hi , may I answer your health queries right now ? Please type your query here... I have had a rash since October 2010. I have gone to the dermatologist 3 to 4 times a week for light treatment. He did take a biopsy of the rash and it came back as an irratate or could be underlining lyme disease. I was put on a antibiotic for the lyme disease but I still have the rash. My primary doctor gave me a CT scan to r/o lymphomia, I doubt very much that I have lymhomia because I have not lost any weight, which my primary said is one of the main causes of lymphomia. Can you help me get rid of the rash? I am on a Antihistimine also.

Thank you
