Had it done (both) in January 13. I was back in the gym 4 weeks later. Initial recovery was THE SUCK. One solid week of mysery. They don’t tell you how bad it’s going to be because I think you would not do it. Took a full 6-9 months for all the residual stuff to fully settle (some of the nerves in the roof of my mouth took a long time to stop tingling). Nothing earth shattering, just a little annoying.
On the plus side, my breathing is WAY better. I immediately saw improvements in all my training. Just more air going in. No more sleepless nights, no more lasting sinus infections. Seriously knocked 12 min off my sprint times (1:30 to 1:40 - longer sprint - 20 mile bike and 700m swim) and I attribute most of that gain just to the ease of breathing. One small hick-up is this I get a LOT of water in my nasal passages when I swim, if I’m not blowing hard out my nose. Just so much room now that the water flows more easily.
So in summary, it was more of a hassle than I thought at first but 9 mos removed, I am VERY happy I did it.
P.S. Buy Neilmed sinus irrigation pack from Costco. Works wonders to clear every thing out post surgery. Still use it every night before bed and I have no drainage/stuffiness issues, even in allergy season.
Peace!
