What new symptoms are these?!

This is interesting because when I was reinfected I was in the backyard of someone's house and felt water dripping down the bottom part of my right leg. I thought I might have been sweating but the next night I saw the bite and had symptoms even though I didn't see a tick. I'm positive it was though. Not sure what that sensation is from.

do you think it is Lyme related? I read that it could be a sign of nerve regeneration or damaged nerves

I'm not even close to a doctor but it sounds like some sort of nerve response. Doesn't sound enjoyable! How frequently do you get it?

It sounds like neuropathy. and can come in many forms. It is very common with both Lyme and Bartonella.
I have experienced: water running down my arm, rain falling on my arms, very cold or hot feeling, numbness, tingling, ice picks, something crawling up my arms, burning feeling, etc...
