Hi Den,
Your GP or nurse will almost certainly ask you to use olive oil for a few days if they look in your lugs and see ear wax........then make an appointment when nice and loose to have it syringed OR you first try using Otex eardrops which can cure earwax, without the need to have syringing.
I'm quite lucky as seeing that i've been DJ'ing for about 28 years now since i was 16, i dont suffer from tinnitus, as always tried protecting my ears when clubbing in loud venues......but i do get ear wax every now and then, which i think is through washing my hair with shampoo and parts may get clogged up in the "wing-nuts", evern though Otex usually clears it up.....but syringing them every so often makes me hear really well again, so is not a bad option either.
Good luck, sweeheart and hope the echoes go away..........if they dont i suggest you call an Exorcist :0)............LOL....
Take care.... love the bear xxx
