I have been hearing in Mono for the past month or so; my left ear has been non-functioning.
So, what to do? I bought myself some expensive drops, and found a syringe that was left-over from some dog medication, and sorted the problem myself.
Several days of oiling the inner workings, then some warm water injected into into the depths, and Bob's your uncle; I hear again. Needless to say, there was quite a bit of muck inside.
I did wonder if a blast of WD40 wouldn't have done the same job as my expensive Cérulyse. WD40 is based on fish oil, whereas the stuff I bought is Lavender and Almond.
Being deaf is very unnerving, it's like living in a parallel universe of exclusion. I feel sorry for those who have to endure a whole life of deafness. Luckily mine was temporary, and I was able to return to my normal state through a very simple procedure.
If only all medical issues were as easy to rectify.
