Hello everyone! I am here to discuss my brother’s condition with all of you. He was discharging thick green colored sputum from his nose and after the X-ray it turned out to be sinusitis. His sinus infection was really bad. He was having sharp sinus pain and was using a nasal spray to get relief from pain. But he could not tolerate it any longer and ultimately he had to go for a sinus operation. I want to know whats sinus surgery recovery time like?
