Hi No1sy- welcome to the board! I am sure you will get lots of posts to help you figure out what is happening.
What you describe sounds like it could be a lot of things and not much like Lyme disease but since some people who come to this board do end up thinking Lyme disease (I know of 3 that in the last 2 months, not counting me, dx'd last month) I am going to post Lyme symptoms ( I am stealing from a knowledgable poster named Ticker) so you can see if they look familiar.
Good luck with your search!
Oh, and don't give up- if you do not think it could be psych, it probably is not. I almost fell for that and I am so glad I didn't. So many of us are told that when the doc can;t figure out what is wrong. Just keep searching till you find a doc that has an open mind and will keep looking. They are hard to find. I never found one- had to use these wonderful boards to narrow down what I thought it could be and target my docs for that disease.
