Your story sounds similar to mine in a lot of ways except that my lyme tests came back positive.

Please make sure that you are using a reliable lab for lyme testing and that you are dealing with a doctor who is familar with lyme. Spinal taps are notorious for false negatives and labs like quest just aren't the labs to use.

My gut tells me that if this started with a tick bite that there is a good chance you contracted lyme and the fact that you took some antibiotics means someone actually thought you did also.

And by the way, a negative lyme test does not mean you don't have lyme...it could mean you are not producing lyme antibodies, etc and also lyme is a clinical diagnosis in some cases.
