As you may be aware, doctors surgeries are no longer performing ear irrigation.   So people are looking elsewhere for treatment options.
I have been doing ear irrigation ( what used to be known as syringing) for about 8 years at the surgery that I work but now do it a lot less.  This is a shame as it's a very rewarding thing to do and usually easily fixed.
The NHS now prefer to treat with Microsuction but this normally comes with a larger fee.
