Hello, i am a 19 yr old young man that has always been decently healthy. I am 5 foot 10 inches and around 160 pounds. For about the last 6 months i have has some weird abdominal pain, It started out with an ache or pulled muscle type feeling (NOT CRAMPS) and from time to time it would go away for a week and them come back for a couple weeks then go away again. Went to the doctors and had a Upper GI and a Lower endoscopy done. They found nothing. I feel like the doctors think i am over reacting but its kinda scary cause now it feels like a dull feeling almost like something inside my stumic. The doctors said i shouldent be worried cause if it was cancer it would have killed me by now. But what should i do would a MRI or CT scan help cause maybe its not in the stumic but on the outside. So idk what should i do?
