My son has had small bumps (they look like bites) on his feet since this morning and it's red around them (mention that it's a little itchy).

It is important to note that if your son has developed red, itchy bumps on his feet after finishing a 10-day course of antibiotics for strep throat and ear infections, it may be a reaction to the medication. It is recommended to consult with a pharmacist or healthcare provider for personalized advice and treatment options.
