I am not if this is the best place to ask, but I'll do it anyway. So I am 18 years old, and I was told by my doctor I had mild gastritis. This all started when I got sick(soar throat, runny nose) one day and I started to take meds, so took Tylenol night, then next day had Tylenol day and slept with a breathe right strip on my nose. The next morning I felt very gassy. Stomach was feeling full of gas(I don't know if it was due to breathe right, because I read online that inhaling too much air can also cause gas). The problem was I wasn't passing gas out, so it stayed in me. Due to the gas staying in me, I didn't eat much for a week. I ate rice and milk maybe once or twice a day and most of the time I stayed very hungry, because didn't want more gas and this kept going for a week. Now after the week I started feeling like there was something stabbing me very lightly all over my front from the chest all the way down to the lower belly, and was feeling a slight warm feeling inside in my stomach(my bowel movements were normal, didn't have diarrhoea and no constipation either). The symptoms weren't severe, they were very light. I would get a warm feeling in my stomach for a few(10-15 seconds) and then it would go away and won't come back till like hours. I got worried(I tend to worry for the smallest things), because I searched this online(biggest mistake ever) and I was very stressed by the results. I was stressing a lot. So I went to the doc and he said yea it seems like you have minor gastritis, the linings are a bit inflamed, but it wasn't anything major. So he gave me Pepcid(It is an antacid), he said I should take it and if it doesn't heal I should come back. So after I finished my medication it was all gone for around a week or so. Since I was stressing soo much before, even after i finished my meds and was feeling better, I was still worried whether my stomach was totally healed or not(So i was still stressing), and now I am getting that slight warm feeling in my stomach again, but this time no heartburn and no stabbing feeling either, just a warm feeling and itching stomach at times(again bowel movements are normal). I am going to a different doc tomorrow to see what happens. So what do you guys think should I be worried?
