Cerebrus, If your whole body began to swell when you took zithro, it's probably because you were having a herxheimer reaction. This happens when there are A LOT of bacteria in your body and suddenly a new antibiotic kills many of them. In this process a lot of toxins are released and the body usually swells up and you could also have psychological reactions as well.
Now if you're allergic that's another story.
I see a naturopath and an MD, they work together. Overall you're going to need antibiotics to get better. I really want to help you man, but I can't until you check out that link I gave you above.
I'm telling you ANY ILADS doctor will be able to help you infinately more than other doctors when it comes to lyme disease.
Check out this forum if you have questions. It's invaluable.

It's a lot like Intensemuscle but for people with lyme. You'd be surprised to see how many people have stories similar to yours. Seriously man, make this your number 1 priority. The longer you have it, the longer it takes to recover and the worse the process will be.
