Hello, The rash on thighs and forearm spreading all over your body is most probably due to any allergy reaction to any plant or cosmetic you used recently. Multiple bowel movements are due to possible bowel infection or any food poisoning associated with allergy rash to me. But, should rule out any other pathologies like intestinal parasitic infection with skin affection. Should run stool culture and sensitivity testing together with fecal examination, and abdominal ultrasound. Take: - oral probiotics - plenty of fluids especially plain water with oral rehydration salts - tasectan for the diarrhea - apply anti-itching ointment locally Discuss this further with your caring doctor. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Albana Sejdini, General & Family Physician
