Ear itching may be a sign of a bacterial or fungal infection
, allergies, trauma,insect bites
It is actually best not to put anything in the ear, even cotton buds because this aggravates and prolongs the problem. If you want to remove wax just place the cotton to the very outside of the ear, it is not to go any further because placing foreign objects into the ear introduces bacteria.
You should consider having a doctor assess the ears to check for infection, if present it can be treated. You can use antihistamines to treat any associated itching.
i hope this helps
