Stomach pain undiagnosed for 3.5 months

I’ve had a hiatal hernia, gerd, and Barrett’s esophagus for 12 years. I’m a 48 year old woman and a Kindergarten teacher, and avid exerciser. My symptoms have been managed by a daily PPI of 20 mg until March of last year. I got a bad stomach infection, was given quadruple therapy with 2 antibiotics and it cleared up immediately. (Wasn’t tested for anything) Following that incident I was sick for most of the year with various coughs and chest infections and was given tons of antibiotics and steroids. Plus I took a lot (probably almost daily) of Motrin for knee pain-which my Ortho dr told me to do. Come November of 2022 I got what felt like another stomach infection. Was given the same quadruple therapy (both times I was never tested for anything). I got extremely sick, vomiting and nausea. In and out of ER with various meds being shoved at me. Nothing helped. Finally GI dr decided to do a scope on me and told me to stop taking the quadruple therapy. As soon as I did the stomach pain was still there but the side effects stopped. Scope showed same previous symptoms-plus no h pylori and no celiac. Said I had gastritis. Told me to take a PpI 40 mg twice a day. It’s not helping. Told to take probiotics-caused excruciating pain so stopped. When I saw my gynecologist about a year ago she told me I had the lowest vitamin D she’s ever seen. Had me start taking a high dose and then we’ll taper. Besides that none of my GI drs have ever checked my vitamin D, B12, or magnesium levels. Stomach pain has not stopped. My stomach is pretty flat in am and by end of day it’s really bloated. Some days are worse than others with the inflammation I can feel and bloating. I’ve changed my lifestyle completely since beginning….no caffeine, no gluten, no sugar, no dairy, no citrus, no fried food. Eat the same things basically daily. 30 grams of fiber (I do poop daily- don’t have issues with constipation or diarrhea). I have an adjustable bed so I can sleep upright. I’m a side sleeper and haven’t since November-if I lay on my side for even a few seconds I get stinging cramping. I eat small meals every 4 hours. I’ve lost 10 pounds so far.
I’ve had a stomach CT scan and it says I have an umbilical hernia-however a recent dr said they don’t think so. I have a scar on my right side of stomach from pyloric stenosis as a baby and a big bulge above it that looks like a hernia….however I’ve had this for years. I can’t sit upright, I can’t wear any type of pants because of construction. I wear dresses daily. My stomach pain moves on a daily basis and is not consistent. Sometimes it’s under my breast bone-gerd. Sometimes it’s across my stomach about an inch above belly button which is along my scar line/hernia line. Sometimes it’s my whole stomach and I feel like I’ve been punched. This week shooting pains started happening from lower stomach shooting up, plus in my left breast.
My drs here are awful. No help at all. Don’t touch me, no exam, don’t test for stuff, just throw medicine at me. I live in FL and am going to Mayo Clinic in Jax in March. If this was anyone else-like my husband-they couldn’t live with the pain. I have a high pain tolerance but am miserable and it’s turned my life upside down. I keep a daily diary just in case. I’ve also never been asked to do an colonoscopy. Anyone else with a similar experience? Any ideas/suggestions?
