I had it done some 18 years ago and would never suggest it. Second hand smoke on people make me gag, I can instantly smell when women are on their menstrual cycle and I have been known to get up and sit somewhere else on the train because someone smelled as if they peed on themselves. But that's not the worst part. After the surgery, had to sleep sitting up and I bled for 2 days straight and you don't even want to know what happened when he pulled what seemed to be 18 inches of gauze out of each side of my nose.
Since then, my sensitivity to perfume/cologne, burning wood/leaves, air fresheners and even fabric softener give me instant migraines. The more I am around any of these scents, my immune system goes down. I've had to ask co-workers to not put scented lotions and perfume on. I have tried air purifiers and now my latest idea was essential oils. They work great, but everyone around me (who for the most part has stopped wearing perfume/cologne and scented lotions) do not like the smell of the oils so I had to stop using it.
I know 2 other people who have had the same surgery and experience the exact same issues.
If I had a chance to do it again, I would opt out of having the surgery. Not smelling is so much better than smelling every little thing.
I have heard that the surgery these days aren’t as evasive as they were 18 years ago, but I’m not sure if those who had surgery recently experience the extreme sensitivity as those of us who have had it so many years ago. I also heard the recovery process was much better now a days too.
