Hi.
Thanks for your query.
Noted the history and understood your concerns.
Recurrent nature of
diarrhea, colon spasm although too severe this time, also having headache, sweating, nausea, fainting all indicate severe intestinal infection.
I would advise your hte following :
Go to ER, get the clinical evaluation for fear of
septicemia as indicated by your symptoms.
Get the blood tests for CBC, kidney and other function, culture and sensitivity.
Tests of stool and urine.
Ultrasonography of the abdomen.
All these will to the severity and cause of the symptoms that you have.
Get proper treatment with intravenous fluids, antibiotics,
metronidazole and probiotics.
