The stomach issue is because of the strong antibiotic, go buy some Floraster, its a probiotic. It will put the good flora back in your gut that is needed. Antibiotics that strong kill all the flora. If the ear problem persists after completing the antibiotic, go back to the dr, he/she can rx a ear drop medication for the ear. My daughter just recently went through this same thing, only she could not hear out of her ear.
