I had an acoustic neuroma, 3.5cm diameter, removed 16 years ago.
The most significant impact is that I had to sacrifice my left ear drum; being totally deaf on that side impacts negatively on my ability to socialise in crowded places. I can’t hold a conversation, however, due to Covid that hasn’t been a problem!
I have benefitted financially as I was granted early retirement from my teaching career and also claimed a significant sum from a critical illness policy.I now run a successful maths tuition business; the only insignificant impact is that my students must sit on my right side which makes it awkward to see what they’re writing if they’re left haded.
