Hi, in my opinion you are having polyp in your nose.
Poylp is usually pale white or light pinkish in colour.
All your neti pot, saline spray, decongestant wont work.
If a patient with your symptoms come to my clinic, I would prescribe, steroid
to be used for about 2 to 6 weeks to shrink the polyp,
Along with this I would recommend steroid tablet also for about 2 weeks.
I would wait for at least 6 weeks for this nasal mass to reduce
If it doesn't, then I would suggest you to get a biopsy
of mass done to rule our any other problem.
