I have a cough that I thought was post nasal drip related (been dealing with this for MONTHS). I can't get thru a sentence without the need to cough, or clear my throat. Also, it is almost like I run out of air mid-sentence. It is embarrassing. The doctors I have seen can't figure it out - they put me on Antibiotics, steroids, gave me an inhaler and nasal spray. Nothing works. Any advice? I am a talker and a singer and I can't do either which is making me very depressed.
