Random long-term cough and post-nasal drip

Yep that sounds like the anxiety cough. The feeling you are describing about being hard to breathe is due to abnormal amounts of carbon dioxide in your body due to habitual hyperventilation. I often experience and hear from others that they can't get a a "satisfying deep breath". That is partially due to the muscles in the back being tight and not letting your diaphragm expand at the amount it would like to. My advice that solved the deep breath problem is to practice the buteyko breathing technique. Instead of taking large breaths, practice taking short breaths for a period of time and then try to take that deep breath that feels like you hit the extra gear. The headache and lightheadedness is more than likely a result of muscle tension from coughing along with the carbon dioxide levels I mentioned earlier. Hope you feel better! I'd also like to mention that your health is incredibly important and even taking a trip to urgent care for a doctor to listen to your lungs with a stethoscope is very important

I have had nasal drip for years along with ringing and buzzing in my left ear. I have been to my regular physician and my ENT physician who have told me not to worry.

Hello. I'm new. I've had a lot of breathing problems and a cough and post nasal drip forever. Drives me crazy sometimes. I'm planning a break fro eating dairy (which is not easy!) just to see if it helps.

Yes i suffer from post nasal drip as well . Especially bothersome at night when laying down , produces morw coughing. Dairy does increase pleghm production .
