I am suffering from nasal blockage for the past 1.5 months. Generally, I have cold and cough problems from past 10 to 12 years, which becomes worse during the weather change. Earlier, I had breathing problem, but have been experiencing nose blockage now. The nose will be blocked from both the sides during the day if I sit in AC room. I feel better if I keep moving or stay in a warm room. The doctor has suggested me to go for surgery. So, I wanted to check if surgery is the only option or can it be treated with medication. Also, I wanted to know if I go for surgery, then what are the risks involved.
