My son who is 5 years old has some sort of redness and some itchy boils on his right ear.

Few days back transparent liquid was oozing out from his ear. It doesn't stink. Doctor has given him some ear drops as he says it is an ear viral infection.

Recently the redness has increased and I could see some boils on the ear lobe and on the face.

Kindly advice

Thanks,
Delon

My advice is to go back to the doctor. This could be many things and without a visual examination I cannot (for the auditory health of a 5 year old) give any recommendation as to what this is.

If the redness has increased that is a major sign that you need to get back to the doctor.

If the redness of the ear increases means it a major sign. What do you mean to say "major sign"

It means you should take your child to the doctor!!

This could be nothing or it could be a serious infection. We cannot diagnose something like this over the internet. A doctor needs to look at the boils again and make sure it is not a bacterial infection.
