Hi, I had de-hydration few days back and I recovered next day. But day before yesterday, I had a severe stomach pain abdomen( just below the chest) and started feeling acidity also, I took lots buttermilk. After 10 minutes pain subsided. I was on butter milk and curd rice whole day. But next day night, I had normal diet and again in the middle of the night, I got the same pain. ( It feels like hurting with knife). I would like to know is it because of de-hydration?
