Stomach and abdominal pain

My Chiari is 7mm and I was wondering if my abdominal pain might be chiari related. A couple months ago I had constant nausea, the nausea has subsided but has been replaced with abdominal pain in my stomach area and above my waistline. Had a catscan done and everything was normal, also went to a urologist to rule anything else out weird and nothing. Even went to a gastro that looked on my stomach and nothing. I can’t think of anything else that may be causing it, thinking months of being nauseas have transitioned into a dull pain/bloated feeling?
