Not sure if any hyperbaric chamber would work, verse the Aviv? THey do not have locations in Arizona. Just want something to help the immune system get regulated again. Covid has disregulated it, and so far doctor's just are not providing enough info to try to remedy some of this stuff for long haulers. Blood work is fine, yet mega brain fog and muscle pains all over, yet was super health before. Any blood tests, medications, etc. that you might recommend please post. Thank you.
