Last week my daughter developed some kind if rash  bump like on her neck and hand. Her pediatrician advised calamine lotion and the rashes were disappearing. Besides, she also had atarax syrup for last 5 days twice, 3.5 .ml. Also we gave her the first dose of deworming medication (for the first time). The next dose is after 10 days. Today, she has a small bump like pimple like thing inside her mouth, I am worried, if this new thing on the left cheek wall near gums is something serious. She had had her food normally and is playful too, but she is irritated on eating anything. Please advise
