Stomachache feels like hunger pain but not hungry

[Nnlinh]

Sometime I have this stomachache that feels like hunger pain but I already ate. 20 years ago I use to have stomach problem (digestion, hunger pain) as a kid and usually take maalox. I don't really have any problem in my 20s and early 30s. Recently I (34f) have had 2 episode of extreme stomachache that feels like hunger. The 1st time (4 months ago) I thought it was because I was hungry and eat something. But the pain didn't go away. So I took gastropulgite and it helps. Today I have another episode. The pain starts 2 hours after dinner and get worsen over time, to the point where I can't stay up straight. I have took gastropulgite and it helps calme down my pain but I still have a very annoying feeling in my stomach. It's mid night here so I won't be able to go have a check up (already book a consultation in the morning).

I just want to be informed and thank you for your help.

The things I've read that can lead to this are food sensitivity and actually eating a bit too much. The other thing I'm wondering about is gastroparesis. https://www.nhs.uk/conditions/gastroparesis/  Here are the symptoms:  

    you often feel full quickly when eating
    you often feel sick or vomit after eating
    you have tummy pain that will not go away or keeps coming back
    you have heartburn most days for 3 weeks or more
    you've been feeling bloated for 3 weeks or more
    you feel bloated regularly (more than 12 times a month)
    you have a swelling or lump in your tummy

Here's a link with more information on it (copy and paste) https://my.clevelandclinic.org/health/diseases/15522-gastroparesis

See if that sounds at all familiar.
