Hi, I was diagnosed as having acid, because I went to see doctor with stomach pains. These have been ongoing for a week now. I live a healthy lifestyle, excercise daily, eat well. Im 31 and 6 3 and 16 and half stones. The thing is I dont think it is acid. Ive had acid before and that is usually higher up towards the chest. This is in my stomach low down and around the stomach area. Feels sore inside but constant. Its managable but uncomfortable. The pain does increase when I eat. I was suffering back pain for a week prior to the stomach pain, but this has subsided and been replaced by the stomach pain.
