I get this crazy spasm like my stomach sucks in by itself and out..I feel like a crazy person when I tell my Dr this..he has absolutely no reply. The muscles in my stomach just go crazy like contractions. I'm so tired od all this. Could be my diaphragm who knows, it does scare me. It only happens when I'm laying down. I start to massage my stomach and change position. Just another thing on my long covid list. I'd like to know if anyone else gets this. Thanks.
