Hello FlossieUK,
You worry that you had neuro symptoms BEFORE the tick bite. Is that it? Reasonable doubt to have. Here are my thoughts:
First, you had symptoms before the first tick bite, that is the first tick bite THAT YOU NOTICED. Many of us were bitten by the tiny nymphal stage tick and did not realize it.
Before your symptoms, did you enjoy walking in meadows, grasslands, pastures and woodlands? How long have you been exposed to ticks? You obviously live in an area where ticks carry Lyme. Where in the UK are you?
Secondly, you have Lyme disease. From the sound of your symptoms, you have the Lyme Neuroborreliosis (LNB) that is far more common in UK and Europe than in the USA. LNB imitates MS very well.
Have you been tested for coinfections? Rowingmom suggested this. I second this because from what I've read, and experienced personally, anitbiotics for Borrelia can be less effective for Bartonella (and other cos). It is possible you have been well treated for Bb but not Bart, Beb, etc.
My husband had brain lesions and was diagnosed with MS and Bell's Palsy, until Lyme testing positive. His Bell's Palsy did not respond to steroids but cleared with 2 weeks of abx. Other symptoms are slowly getting better. He still has some dizziness too.
But we too have wondered whether he had MS and then got a tick bite. But so much of his MS presentation was atypical: confluent brain lesions, rapid onset after tick exposure, no oligoclonal bands in CSF, etc. And so much has improved with antibiotics that we are moving forward with the belief that it is not MS, even when we can't know for certain.
We live in the US, but both got Lyme and coinfections while hiking (fell walking) in the Lake District and Scottish Highlands in June of 2014. I found this article which suggests criteria for interpreting Lyme testing in Scotland:
http://jmm.sgmjournals.org/content/54/12/1139.full
Scottish, like European WB criteria, is SO different from CDC. 2 Bands + 41 = pos And they consider IND bands as weak positive (but give them less weight). For Scotland, these are the Lyme specific bands for IgG:
18, 22, 26, 30, 32, 34, 39, 46, 58 and 92 kDa (my IgM had 18, 31, 34, 39, 41, 58)
Whether your IgM Western Blot is CDC positive or not depends on how soon you were tested after your tick bite. What I understand is that medical orthodoxy believes a positive IgM is not truly positive for Lyme more than four weeks after bite. I guess they think we have Lyme symptoms and Lyme IgM antibodies, just not Lyme disease.
Best of luck to you.
