For what it's worth, I think you need an answer from a specialist.
From my own experiences, and from the experiences of others I know who've had Lymes, getting diagnosed has been really, really tricky and I don't think you're going to get the answer on here.
As proof of this, I got a tick bite last month which displayed atypical symptoms. I went to see a doctor shortly after who dismissed them, then went to see another a few days on who took it more seriously. It didn't have a bullseye, but did have a rash, and therefore ticked some of the boxes and not others. Thankfully the second doctor was far more familiar with Lymes than the first, so was far more aware of the issues, and that the fact that if it was Lymes it'd be pretty bad in the long run - hence prescribing a course of doxycycline. I'll never know if I actually had it, but I can at least be sure I won't as a result of the treatment.
Whilst I'm aware this is quite different to your case I would highly recommend seeing a doctor again. I would also recommend anyone who has a bite that's even vaguely suspicious not just to see their doctor, but encourage them to take it seriously.
Apologies for taking your original post on a slight tangent. I've got all my fingers crossed for you.
