Bandgirl, have you been tested for Lyme by a Lyme specialist? I had the same issues
and sound out two months ago that I had late stage Lyme. The fact that you have joint issues on top of being tired all the time tells me that Lyme might be behind what you’re experiencing. Not sure where you live, but it’s worth the trip to a Lyme specialist who will perform the screening tests for Lyme that other doctors might miss. Good luck to you. None of this is easy.
