Hello, I recently found out that i have chronic gastritis due to the results of an endoscopy and ultrasound of the abdomen. He said that there is no infection just an inflammation. The doctor precribed me Nexium and said to take it for about 6 weeks and i should be good, completly healed he says. But, i am alittle skeptical about it, today is my second day taking Nexium and i actually feel worse then i did before taking it. Last night i had a very rough night, i had extreme stomach discomfot, slight nausea and i felt like i had some indigestion and gas stuck in my upper abdomen. Is this normal to be happening ? Should i continue taking the Nexium like prescribed ? Will i be completly healed after 6-8 weeks of using this PPI treatment(Nexium). I am only 23 years old and i was always a healthy kid, I just want to get back to normal.
