TMI but oh well lol

I’m 1 month PP, C-Section. For the last couple days I’ve noticed that when I eat food not long after I get this terrible stomach ache/pain where the only way I can sort of get rid of it is to crouch down where my knees would touch my chest. And that’s ONLY with solid food. If I’m eating something with soup I’m perfectly fine. First 2 maybe 3 weeks out of the hospital nothing like this occurred only recently. What could possibly be the cause? Is it normal for pp C-Section?
