My Daughter Treated A Mil Measles Attack About Two Months

my daughter treated a mil measles attack about two months ago. But since then, she has had bouts of stomach ache and body itching. I have used many body creams and also drugs for her stomach which usually attacks her in the night but have not suceeded. I have used loratidine,...Most recently, she has had a smelly burb and then she just vomited now. Please what else should i give her?
