i have a 4 year old with swollen tonsils and a cough~ she also has a mild rash below her mouth it started on one side and kinda spread across her chin, it is dry and rough and looks chapped if you will, not sure i though possibly a food allergy, should we see a dr. its been 3 days, its not getting worse, i can discern the cough and tonsils we have been down this road a few times, thanks
