I had a colonscopy on 12/28 and 3 days after that I started getting sick. Either once in the morining after I eat breakfast or sometimes in the evening after dinner, I will start getting cramping, then dirarea and vomiting for at least 2 hours. I went to the doctor and she says it was just stress on my colon from the colonoscopy and it should go away. Well it's been almost a month and it still hasn't gone away and I'm tired of getting sick almost everyday. Has anyone experience this and how long will this continue?
