Sensitive/sore stomach?

[Justkoko]

Anyone had issues with a sore or sensitive stomach with covid? My digestion is shot, I've been a bag of wind every evening and now my stomach is feeling a bit tender when I eat. Not sure if sugar is making it worse or wheat, or nothing in particular. Feels like when I have had gastric flu in the past.
Anyone had this? Could it have sent my good bacteria into disarray?

My day 0 I was burping loads and had reflux my abdominal pain and I never burp. It was all kind of trapped, so strange. That lasted until day 1 and every evening I have excess wind (not burps!) which is unusual for me.

I am eating healthily, taking vitamins and acidophilus x
