I have been having horrible stomach ache no other symptoms what do i have.? and how can i get rid of it.

Stress gastritis: At your young age, living in the US, and guessing you are routinely in general good health, the most likely diagnosis is gastritis. The easiest treatment, besides removing stress (which many times is difficult) is to: 1. Water or Club soda 3 times a day 2. An apple in the evening 3. Any antacid that starts with the letter M: Mylanta/MOM/Maalox shot glass in between meals 4. No spicy foods!
