I had covid 10/2019 cold nodule sinus, after covid cleared I had the WORST sinus infection in my life with the WORST headache EVER! During sickness I lost 20 lbs, but a month after recovery, I gained those 20 back and kept gaining. I peeked at almost 40 lbs over pre covid weight, I exorcise more and I eat less, but I can't lose those 40 lbs, my baseline heartrate (post covid) at rest is 100-110, with light exercise it jumps up to 150-160 range, all my cardiologist said was I was fat and needed MORE exercise, after 2 years brain fog and short term memory are still effected
