My husband has stomach ache in an oval shape that starts from belly button and a few inches above.(started yesterday) He says it feels like gas and he burps a lot with no relief. Even after the gassy feeling goes the pain stays for a couple of days and it's uncomfortable for him to move around. I'm not sure if it's from food as I have not been able to find a pattern to this. It has happened before also, we assumed it could be because of dal but then it happened when he did eat dal too. He did eat some extra spicy food day before yesterday (didn't realise how spicy it was before eating and he didn't want to waste it once it was too spicey) He drinks enough water around 2.5 - 3 litres per day. Plz advice. Thank you
