Has anyone had an operation called Fess? General anaesthetic then a scope with surgical end to open up my sinuses which he thinks may be blocked blocked or swollen stopping me able me to blow my noses instead i it’s always a pot nasal drip. When I use all the usual meds and was put ona week of steroid tablets then 6 months of continual steroid nasal spray had to stop as it gave me dreadful depression alternating with panics after a week of stopping back to normal. I don’t know what to expect with op or continue choking on mucous?
