Thanks for posting your query.
Do you have spasmodic abdominal pain/ fever/ decreased urine output?
You have most likely infected with some intestinal viral/ bacterial infection i.e. acute gastroenteritis
You should consult with physician and dermatologist
simultaneously & should get thorough check up.
You should maintain hydration by taking oral rehydration solution and maintain adequate urine output.
You should also take antibiotic course, anti-spasmodics and probiotics.
You should also avoid milk and all milk related products such as butter, yogurt, cheese.
