I've Been Having Pains In My Gut Area For 3

I've been having pains in my gut area for 3 days. It feels like food will not digest and anything I drink sits in my stomach under rib cage. I don't drink alcohol or smoke and am very careful with my food choices. I was better all day until about 5 pm. I know it's not easy to recommend treatment because you don't know me but am trying herbal tea now. Any other suggestions ?
