Please do not solicit medical advice from the internet. If you are concerned, go to a minute-clinic or other doc-in-a-box. It's much cheaper than the ER, and they'll tell you if there's anything to worry about.
OP, please go see a medical professional. My Mom ignored a similar problem for 3 months and it ended up being a rare type of appendix cancer. The three months was just long enough for it to go stage 4 and become inoperable. Just go and know for sure.
Please listen to me - stomach distension should ALWAYS be checked by a medical professional. One of my kids had slightly distended stomach which we attributed to a big rib cage and still needing to grow into his bigger frame.
It was a mature teratoma weighing over 20lbs
He had a physical with no issues just three days before we visited the ER for stomach pain. ER found it immediately when they noted the stomach distension during his exam and did scans to find out why.
Maybe it’s nothing. Maybe it’s gas. But also maybe you devoured your twin in the womb and he’s back for revenge.
Please see a doctor and ask for an ultrasound at the very least.
I asked my pharmacist and I decided on/did 1) miralax + 2) mineral oil + 3) glass of magnesium citrate Calm sleep stuff Im about to down + 4) I might mix in some of that bulk fibre stuff in the orange container into my ginger ale
