Clip: “but in the last two or so weeks, they have caused my ear to be rather itchy”. No, it’s not the HAs that are causing the itchiness. The enemy of ear canals is moisture, which provides a nice Petri dish for incubating bacteria and fungi. Moisture can be introduced in any number of ways, limited only by your imagination, but showering, face-washing and adjacent perspiration (sometimes but not always) coupled with contaminated hearing aids are the main causes.
Buy a Dry-and-Store; the one with the UV light, buy some appropriate ear drops, and plug your ears while showering. These measures will go a long way in the right direction. In case you haven’t noticed, ENT doctors are not so quick to flush out ear wax anymore, fishing it out with a tool instead to encourage a dry canal.
Good luck.
