hi, im m 32. with no background on digestion problems. 187 cm height and 100 kilograms weight,; it has been 10 days now that i feel a bad pain in my stomach - becomes worse at night - without any signs of diarrhea, sickness or other symptoms, just the pain thats it, i have had Checkup tests and all is ok. what could be the origin of this unknown pain exactly in my stomach? ((by the way, i have tried clinidium,digestive , omeprazole, aluminium gs , and none of them could stop it. even i tried Colofac. because i thought it may be because of stress and a kind of spasm, but none of them changed the condition))
