I offer this warning advisory for those regularly using IEM's...
I've been completely deaf in my left Ear for the past 10 days. It has been a very unpleasant, and at times, painful experience.
Given the present (UK) lockdown restrictions, I was reluctant to visit my local Doctor's Surgery for assistance.
Alternatively, I followed online advice by administering regular water irrigation, and by regular dosing of my Ear with Sodium Bicarbonate drops. It's only after 10 days that I have been able to fully extract the impacted Wax from my Ear (the drops soften the Wax, and water irrigation flushes the resultant debris).
Not many Doctor's Surgeries offer free assistance in undertaking Ear syringing - while many charge privately. Both Boots and Specsavers charge £50 to clean each Ear.
I regularly listen to various podcasts and music on the go using my IEM's: this, it would appear, from online advice, is the likely cause of my 'Impacted Ear'. Apparently, it is an issue experienced by regular use of Earbuds and IEM's - and by Hearing Aid users. That is, the natural extraction of Wax from the Ear is severely inhibited by prolonged wearing of Earbuds and IEM's.
