What Causes Peptic Duodenal Ulcer And Terrible Pain In Lower Left Quad?

Question: I have been sick with flu-like symptoms since October of last year. I feel like I have the flu and it just won't end. I'm tired all the time, cold all the time. off and on my tongue turns white my stomach issues won't clear up. I get patches of skin as large as 10 sq in that are painful to touch like a typical viral infection.

Background: I was working very hard on a project and living out of a hotel. I ended up in the ER with a peptic duodenal ulcer and a terrible pain in my lower left quad. I also had a very bad case of dandruff that all seemed to start at the same time. At the time I was admitted, my blood sugar was very high 350 and my liver function was also high. Given metfromin, omeprazole and did a round of ciprofloxacin and metronidazole because the theory was it was probably diverticulitis (but was not). Ultimately, I improved but I still feel sick.

Since then: I have had a CT scan (normal) Scoped both top and bottom (normal). Found small amount of blood in urine so did a urogram and got scoped there too. Minor swelling of prostate likely cause, but otherwise all that checks out. As of XXXXXXX 1, my liver numbers are normal. I've stopped taking blood sugar meds completely A1C is 5.9 but my morning (fasting) blood sugar will be 90 and the next day with same diet over 150. Just completely exhausted all the time. Ulcer seems to have subsided but my small intestine is "sensitive". Carbs really make it worse. Have also had a lot of blood work except nobody has done endocrine study yet. All blood work is normal and WBC is only ever so slightly elevated.

Last Wed: I finally felt well enough to go on a one-day marketing trip where I was running all over XXXXXXX for the day. Then, I spent three days in bed, stomach is worse, tongue turned white again, side started hurting again. Left side has a patch that is just painful to even touch and I hurt all over and I'm freezing.

I am seeing a GP and GI specialist. I feel like the two of them don't want to get in each other's way but neither is getting the larger picture. I'm only working 5-6 hours a day and napping 2 hours a day, can't sleep at night. Going nuts and loosing my business because I can't get anything done. Both these guys tell me to wait it out, I'm getting better but they don't understand how BAD I really feel. I'm getting desperate for a solution.
