Hi! Hoping for a bit of advice. Since November 2017 I've had a blocked nose and crackly chest which is worse at night. At first I assumed it was a lingering cold and ignored it but it's been 4 months now and is getting progressively worse. I'm uncomfortable and breathless throughout the day and my sleep is affected as I regularly wake up feeling like I'm being smothered. Vicks is my new best friend, I've tried decongestants but they don't touch it. Any ideas what this could be? And if I go to my GP will I be dismissed as a time waster with a cold? Thanks!
