I live in NC but my Lyme doctor is in NH. Back in October I started on abx again for what I presumed was my Lyme symptoms coming back. A month after on abx a rash appeared on my back which is where I was originally bit in June of 2012. We took pictures to show the doctor. It was blotchy, streaky and had "cat scratch" like marks. It would last 4 or 5 days then scab over and disappear. This went on every month and we were sure to take pictures. I wasn't feeling any better on the abx so when I went to see my doctor last week I had every intention of giving up the meds and saying thanks to the doctor. Well on the day of my appt. luckily the rash was in full bloom. He finally got to see the rash in person and said immediately it was a Bartonella rash. He has now put me on Rifampin and Factive which is a combo I have not had before. I previously was on Zithro and Bactrim which did nothing. I still feel that CFS is my main illness and no amount of abx is going to help with my most disabling symptoms. I will give this another go and see if it helps in any possible way. Even 10 percent would be a help....I am not sure why this rash keeps appearing but seems to only happen when I am taking abx so I am assuming the meds are stirring up the infection and presenting itself as a rash or it is a herx appearing as the rash.
