question: I have a normal sized zit on my upper back. I have been getting it there for years. In the past it would only be once every couple of months but now twice a month. I was diagnosed with lymes disease and a couple co infections six months ago and am still on antibiotics, antimicrobials and many herbal supplements. I m not sure if its related to the Lyme rash I get on my lower back. That rash is a whole patch of itchy blisters of clear fluid that come and go once a month when I m herxing. But the zit is a white head zit of about a medium size that I get some white puss out of when I scratch it off. Any thoughts on what it might be caused by or if its related to the Lyme rash?
