Hello, I've had an endoscopic sinus surgery and septoplasty some days ago. My doctor didn't gave me any specific guidance, and I've had sex with my wife from the 2nd day after surgery. I saw some websites which prohibited patients from strenuous activities as sex, so I was wondering if it is so harmful? And if yes why? or it will just cause bleeding from sinuses? I have headache now, and I'm really worried so any help is so appreciated! Thanks in advance for your attention!
