Hello, i am a 30 year old woman. no medical concerns that require medication or treatment (that i am aware of) For the past 3 days i have been suffering from severe stomach pain and diarrhea. within 60 minutes after i eat anything, be it fruit, sandwiches, meat, vegetables, cereal, etc. you name it. 60 minutes afterwards i am on the toilet for roughly 30 – 40 minutes with intense painful diarrhea, and before that severe stomach pain, afterwards i have stomach pain as well. i am scared to eat anything… what could this be?
