I'm really struggling with a chronic dry cough that's been bothering me for 23 years now. I have these intense coughing fits and throat irritation at least 10 times a day, and it's really getting to me mentally and even makes my muscles hurt. I don't smoke or drink and my chest X-ray was all clear. They've found DNS and sinusitis through a nasal endoscopy, and I can't help but wonder if they're causing the chronic cough. I've tried meds for GERD and allergies, and while cough medicine helps a bit, the cough always comes back just as strong. Could you please share some insights because I'm really at a loss here?

take treatment for sinusitis, reduce the infection.
