Interesting. I feel like I had Covid before they came out with announcing what it even was. This happened to me in Nov./Dec. 2019. The doctor didn't know what was wrong with me. Shortness of breath, malaise, just not well but not super sick. I'm athletic and exercise 6 days a week and do my best to take care of myself. This phenomenon eventually passed and I have also had a weight loss of about 10 pounds. I thought it might be because I contracted C-diff after taking Clyndamycin for a dental issue. That was horrible and very scary to survive. I am much better now but am still maintaining the lower weight. Not necessarily trying to, it's just happening. Maybe it does stem back from the "Covid", I really don't know. I still feel also, like I have rapid heart beat at times that I never had before. I guess only time will tell. I also deal with a tortuous intestine and this has added complications. I'm doing well and I hope that you do too. It will be interesting to see if there are others that share their experiences. I hope so.
