I haven't been on here very long, but that looks like a suspicious rash. It's worth it to get to a doctor soon and see if they will get you on at least a months worth of abx. At least ask them about
it. From all the research I've done and all the literature from ILIADS website & Lymedisease.org, they have said it can be cured
in less than a few weeks if caught early with certain abx's, approximately 30 days.
Best advice see doctor first, contact the experts at ILAIDS or lymedisease.org
Hope that helps.
I sure wish I had known that way back when.
