Yep had m too. Never had it before I got bit by a tick and got Lyme. Ofcourse my doc cannot explain it. I tested vitamin B a couple of times and never had a deficiency.
I usually get one after I consumed a few beers. I noticed that I got it a couple of times after I went to a birthday party and had a minor alchohol buzz. Don't know if the alchohol does something to upset my metabolism. Maybe vitamin B after all? Maybe candida from the antibiotics? Although I've been off them for quite a while now and only had 30 days oral. I had them more frequently since I allowed myself to consume alchohol again, when I started feeling healthy enough to give myself "permission" to do so.
It's not the most serious of symptoms but what annoys me is that it's another one of those vague weird complaints, like my creaking joints or muscle fasculations. And ofcourse no one can tell you whether or not you still actually have active Lyme or not. Long live the antibody tests
