6 weeks ago I started having post nasal drip and then it would feel like it was all in my throat and I would get short of breath. Now I still have the mucus problem and still get short of breath when it feels like the mucus is thick in my throat. I have been diagnosed as having asthma....allergies...chronic bronchitis.....and gerd by 4 different doctors. I have had chest xrays taken and they have came back just fine....bloodwork just fine. I have never had any cough whatsoever. so I am not sure what I have and I am sick of going to the docotrs and getting different diagnosis. could someone please help me here?
