Hello dear, The symptoms as mentioned in your post is attributed to either infection or inflammation in the Gastrointestinal tract. The sensation of numbness, hot & cold flashes can be attributed to loss of fluid & electrolytes from the body. Presenting with such symptoms, I usually treat my patients with: 1. Tablet Pantoprazole + Domperidone twice daily (to be taken half an hour before food) 2. Anti spasmodics like Dicyclomine preparation twice daily (to be taken after food). 3. Antibiotics like Ofloxacin+Ornidazole preparation twice daily (to be taken after food) 4. Oral Rehydration Solution (ORS) for maintaining the hydration status of the body. 5. Take soft, plain, non-spicy foods 6. Avoid fast foods & gas producing food products like cabbage, etc. If symptoms still persist, it will be better to consult a Gastroenterologist & get a proper physical examination done. Investigations like complete blood count, stool examination & Ultrasound scan of abdomen will be helpful in detecting any pathological cause for the symptoms. There is no need to worry, he will be fine. Wishing a good health. Take care.
