A week and a half ago I posted that I was feelling really well with the abx, but I don't know what it can be, but this week I has been sick all week, really bad on wednesday, yesterday better but not well and today bad again. When I have herx in the past have been max 3 days, but the average 1 or 2 days. I don't think is the lyme, I blame it on a virus I got. I am in my last days of the months abx. Has anyone has had a similar experienece that when finally when you are feeling better, you go backwards and feel the worst?
