I Had A Colonoscopy In February Of This Year And

I had a colonoscopy in February of this year and ever since then I've had stomach problems. 3 hours after I eat I get indigestion. Based on the food types, sometime is worse than others. Simple meal tonight was baked fish fillets, mixed vegetables and seasoned and baked curly fries. Now I feel like the food is still there. My stool are soft but not runny..
