Alot of your symptoms sound familiar to me, but I wanted to comment on your arm pain. I was treated for two years for my Lyme and have recently began to relapse. This is a symptom I have been having in my left upper arm - it is sore when I am typing (which is my job), when I reach for things, if I move wrong and I don't sleep on that side so I know it's not because I slept on it funny or anything. It's like in my tricep muscle or upper arm area and spreads. Is this what yours is like?
I will be anxious to hear others comments on this also. Sounds like you need a Lyme test though. I am sure others will come along and give you all the info. Also there are links at the tops for the newbies (basics) that has some great info. I hope you start feeling better soon.
