Suggest Remedy For Indigestion And Pain In Stomach Area

I always have indigestion even when I get up in the morning with pain in my left side. I feel alot of pain in the stomach area. Sometimes it s like the food is getting stuck in there. I just took my gallbladder off two weeks ago. Am not pregnant I tied up my tubes 7 years ago. Please help me. I have gone through a lot of testes but they always find nothing apart from my gallbladder issue. What can this be? I appreciate your help. Thank you.
