I Am Having Extreme Stomach Discomfort For A Few Hours
Can be a serious problem and not just intolerance.
Thanks for your query.
Noted your detailed history and understood the concerns.
Too much severe pain due to intolerance is rare.
Hence it would be prudent to visit ER or nearby hospital to have proper clinical examination, evaluation and investigations:
X-ray of abdomen in standing position and Ultrasound of abdomen along with tests of stool, blood and urine will help to confirm or rule out any cause that is causing so much pain.
For me this is an urgent one.
Please give feedback once all these things are done.
Do not take anything orally till you see a Doctor and investigated.
