Stomach Pain and Bloating with EDS and POTS

Stomach issues from EDS and/or POTS. I posted a while back about how I don’t eat or drink a lot bc of the bloating and fullness I get. This week I’ve started having pain, like a dull soreness (on my left side mostly) when I feel bloated/full. I’ve also been struggling with constipation and just overall feeling like I have no room in my stomach. Years ago I had pain and went to the ER who told me it was related to constipation. This feels a bit similar. But I’m curious if this is something others have had. I get nauseous but don’t throw up and I still make myself eat enough to be okay. It’s just uncomfortable I mostly snack a lot. Some suggested gastroparesis on my last post and it seems like I could check off a lot of those boxes. It seems to flare up like this but it’s not always this bad. Just looking to see if others experience this.
