When I was first tested for lyme I had only one band show up so they told me I did not have lyme and had "emotional issues" and to seek therapy. Well, I knew I was sick and that was not true. I ended up going from Dr. to Dr. until I finally got my lyme diagnosis based on my symptoms. By this time a couple years had passed and I had gotten a lot worse and had most symptoms other than joint pain. When I had another western blot done after my diagnosis, I had all strains and all bands positive for lyme. I also ruled out pretty much ever other possible illness that would cause those symptoms. Keep on fighting for yourself. Don't let one Dr. tell you no. In my mind, if one band shows up then you must have it otherwise none would show. That's how I saw it for me. If that Dr. had said, well you need 3 bands and you only have one so you don't have it, well then why did I have one and yes I did have it, it just wasn't full blown then and I ended up going years more letting it get worse with no treatment which made it harder to get better.
