I start having a hurting in my stomach as soon as I eat fruit and it hits my stomache, stomache will feel like it is tighting up in a ball, I'll also get the feeling like I'm dry heaving. It will last for a few mintues then go away. I've also had this hurting when I haven't eaten anything. What can be causing this?
Sounds like an ulcer or maybe GERD (GastroEsophgealRefluxDisease). At any rate, see your doctor for tests. You may need to see a Gastroentorologist. I am not a doctor, I only play one on the internet. I am going through this with my son now though. Fruits are very acidic and could cause an ulcer or GERD to flair up. Go get some tests done and Good Luck.
