Oh my goodness, poor you … yes … you need to get that addressed before things will improve properly.
Yes, do consider changing to a less physical job - my thoughts on this is that you end up with some inner ear hydrops after such procedures because you inevitably get a leak, which will take a long time to rebalance, and heavy lifting exacerbates mine … your mileage may vary.
I think I should clarify that my advice to be conservative is aimed towards those who’ve had mild trauma, not a cholesteatoma.
A lot of people think they have PLF whereas the real culprit may be the hydrops it leaves behind I suspect. No amount of surgery on the outside can fix that. This may be one of the reasons why there has been so much controversy.
But in any case always discuss this with a qualified expert before making a decision.
Best of luck with it!
