I did recently, for the second time in maybe 5 years. The hearing was starting to fade, the high freq were gone and sometimes my ears went silent. The doctor pulled out the dirt in a minute and I was ready to enjoy music again.
My guitar played just had his cleaned and said it was disgusting how much crud came out. he feels great and can hear great now. I'm itching myself to give it a go.
Do a search though as this was brought up a while back.
Spa's also do the "Ear Candling" but i'm not sure which is best.
I've had it done twice in my life after sinusitis-type illnesses, and yes, it's amazing.
However, I did once turn up to the surgery *asking* to have it done as I thought my hearing was getting dull and was turned away - the nurse said it was dangerous for the eardrums if not actually required. Maybe that was just BS to save NHS money (I was in the UK then), but just a potential word of warning.
The wax is in there for a reason. It's for protection.
If your going to get your ears cleaned out, use caution afterwards. Take the opportunity to start taking better care of your ears and get a nice set of ear plugs as well.
