Hi Eyal,
Welcome to LymeNet.I know you said having a diagnosis of Lyme disease seems like it "is a big stretch."
But for many of us, your having a diagnosis of Parkinson's could be considered "a big stretch." It's all in how you look at something.
When symptoms are the same for different diseases, it's difficult to know what's really going on.
It's a well established fact that the Lyme tests can be negative when a person actually has the disease.
If Dr B (in PA) diagnosed Lyme based on your 2nd test being "overwhelmingly positive", along with the neurological symptoms you have, then I would consider his diagnosis to be correct. Lyme is supposed to be a "clinical diagnosis."
Most cases of Lyme do not fit the textbook descriptions of the disease.
Ex: My father only had Alzheimer's symptoms, but he had Neuroborreliosis - neurological Lyme disease.
Because he was mis-diagnosed for so long & we had so many complications (especially his age, our ignorance of LD & the LLMD was in NJ, no Lyme dr in SC) we stopped his treatment. A few years later, he died of complications of Lyme.
You are indeed fortunate - you have a Lyme Literate Medical Dr (LLMD), a positive test for Lyme, & you're on antibiotic treatment.
As for any irreversable effects of long term antibiotics -
Your LLMD will do routine blood work to monitor your condition.
If you adjust your diet & take adequate amts of Acidophilus to replenish the good bacteria in your system, then you should keep the candida under control.
The risk of these problems is minimal compared to the problems you'll develop if you do not get adequate treatment for this disease.
I hope this will help to dispel your fears about antibiotic treatment.
I don't know your LLMD personally, but a good recommendation for him is the fact he's one of the Directors for the International Lyme & Associated Diseases Society. www.ilads.org
Maybe some of his patients can answer your questions.
