Mayo says it’s not a chronic virus. However, another doctor in Texas says research shows otherwise. Idk. Looking back, I’ve had these symptoms for 15+ years but was never diagnosed. I finally had to retire early because I would sleep all weekend and then make it to work Monday and Tuesday and maybe half day on Wednesday. Then I’d start all over after sleeping Thursday, Friday, Saturday, and Sunday. Mayo dismissed many diagnoses and I am feeling better, but it’s a total management thing. My daughter is better than me. Doctor says it’s because of the age. I wish your son the best. I highly recommend a visit to Mayo! I’d be glad to talk with you more about our symptoms and various treatments we have tried.
