I had long covid for a long time and heart inflammation, have been mostly better for about a year, just had a virus (covid test was negative) and my chest feels awful again. It's so similar to before, a heaviness and I feel so tired. Worried and wondered if anyone has had similar and come through it quickly, I don't know how much to rest as I don't trust my body and scared I could over do it and end up back where I was. Thanks
