I had a bad cough and head congestion 3 weeks ago. However, everyday I feel like I have a great deal of mucus in my throat that I can t clear. I cough frequently, but it s not productive. It s hard to sleep because of this condition as well. I have, in the past, been treated for laryngeal reflex, but it had been much better over the last couple of years. What can I do to improve this - it s causes a lot of discomfort and difficulty even swallowing. Thank you for any assistance you can offer.
