Hi. Thanks for your query. Noted the history of awful belly cramps, vomiting and diarrhea; lips, face, hands and feet swelled up and had bright red itchy arms and legs. Felt like dying, as there was burning hot and sweating, chilly later, then subsided, now okay. All these symptoms are indicating of a septicemia or bacterimia attack. Since you have had diarrhea and vomiting along with feeling hot, seating , then chilly and also the other symptoms indicated that you have severe gastroenteritis. The bacteria and/or toxins released thus and absorbed into the blood stream reach the whole body give all the signs and signs. I would advise you the following in such a situation: First of all, send the sample of blood for CBC, culture and sensitivity, Kidney and liver functions. Also send urine and stool samples. Get a clinical evaluation and examination to get started on a proper course of an antibiotic. Metronidazole, probiotics. If needed get admitted so that intravenous antibiotics, fluids and electrolytes can be given Continue the treatment till you are cured.
