The condition is really no fun at all.
The surgery is straightforward and common in aircrew.
The post op follow up treatment (involving a small vacuum cleaner) was a bit white knuckle but beneficial.
No problem with Class One Medical renewal.
I would call it a good investment, glad I did it. With that behind you the nose sprays and sinus rinse etc have some hope of working, should they be required.
I still regularly squirt salt water up my nose to stay out of trouble.
