Welcome to our community! I'm so glad you found us.
If you haven't yet, it would be helpful for you to start with reading through the thread at the top of the forum titled,"New to Lyme?...Start here!!", as it is packed full of important information, symptom lists, helpful links and pdf's, how to detox when one has these infections, information on probiotics and much more. And this is another good list of possible detoxing routines: www.tiredoflyme.com/detox-methods.html
How long were you taking the Doxy, Azith, Tindy, Mino and how long since you stopped taking those? It's possible that you weren't in treatment for long enough and the infection has returned.
You can expect your Western Blot bands to change around pretty much every time you get one. This is because of the lack of sensitivity of the testing as well as the nature of the bacteria - which changes it's outer surface protein from time to time, unlike other bacteria.
When we get a blood test, we have to remember it's like a snapshot in time - it only tells us what's going on at that moment with these infections. It could be that there weren't enough antibodies being produced just weren't high enough in quantity for these inadequate tests to "see".
