Yeah, I've been feeling poorly for quite a while, and just got treated with antibiotics for Lyme Disease as a precaution while I wait for blood work results. My doc says the blood test sucks, and almost always come back negative even when positive. Said it also could have been covid... possibly long covid... in other words, no idea. Feeling better than I was, though. Not great, but better. Had bad body aches, headaches, heart palpitations, shortness of breath and very low energy, and all that has improved.
