Hi..did you try the naltrexone? I just got it prescribed yesterday during my visit at Mayo post Covid Care. I was told they are seeing good results in studies with long covid, MS, chronic fatique, Inflammation , crohn's, IBD patients. I got Covid December 2021. It attacked my immune system and brought on severe ulcerative colitis, along with many other symptoms. I had covid toes , and my toes are still numb, painful, red and swollen. I hope and pray that someday they can help all of us with this syndrome. I have been in a flare since December of 2021. There is no stopping this disease. I have failed various therapy due to horrible side effects of the drugs. My doctor prescribed 1.5 mg capsules that are compounded at the Mayo pharmacy. Of course, my insurance will not pay for it. I am going to try it . I am desperate for any help I can get.Could you get back to me and let me know anything about this treatment. Thanks for your time. Sincerely..Kitty2
