I had COVID in March of 2020 as well. I still have heart palpitations, sporadic shortness of breath, extreme allergies including skin lesions/rashes, bone dry sinuses and skin, fatigue, exercise malaise, and mild to extreme pain in joints from overall inflammation. I originally had difficulty walking from the bedroom to the kitchen for about two years, then could walk around the block on a good day and now on low dose naltrexone, I can walk about 2/3 of a mile about 6 days a week and can finally lose the COVID weight. Naltrexone works slowly but after a month I can see the weight loss and feel the increased energy. I still have to be careful as if I do too much, I am down for the next 2-3 days.
