You should go for surgery or not can be decided only after seeing your CT scan
You have symptoms all the time like nasal blockage, voice problems.
so surgery is advised if you have ct scan findings
You can discuss with your doctor about need for surgery.
You can take medication for long but if the disease persists then complications may may develop.
The important point is that allergic symptoms may not decrease complitely but anatomic problems like nasal blockage will get relieved.
