I have countinous stomach ache in upper left part. When I lie down problem aggravates also the pain is mild but keeps on extending from upper left abdomen to left down. Cannot sleep because of it. Excees burping but not farts as such . Was on acidiy medication but doesn't feel like acidity anymore. No vomiting no problem in passing still but frequency increased. also pain increases if I lift something heavy or jump. And most weird thing if I drink cold or hot water I feel that cool or hot in my stomach.
