Question: Why do my new hearing aids cause my ear canals to itch?
Answer: If itchiness in the ear canal persists for more than a few days, you may need to change the size of the silicone domes that are attached to the hearing aids that sit within the canal. However, if your earpiece is a custom hard acrylic shell, you may consider having this remade in a hypoallergenic material. For practical everyday precaution, it is wise to use antibacterial wipes made specifically for hearing aids, and wipe the earpiece, before you insert the hearing aid in your ear. There are also drying kits with UV lighting which kills surface bacteria in which you can place your hearing aids at night.
