I've had this horrible problem since 2007 following a severe sinus infection. It took doctors 2 years to diagnose it. I was tested for GERD, asthma, allergy, all negative. I have had mild success with Gabapentin (300mg/3 per day) combined with Amitriptyline (10mg/2 per day) but I still cough a great deal, especially in the mornings and after I eat a meal. I will definitely be trying ZARBEE's cough syrup as suggested by texanna in the previous post. I too have pulled muscles and made myself sick by coughing so hard. I'm tempted to increase the dosage on the Gabapetin if the doctor is willing. I always get the feeling that the doctors just wish you would go away. I'm seeing a PA in an ENT office and he is the first person I've seen that has taken an interest and listens to me.
It remains to be seen if he has any suggestions other than what I've heard for the past 11 years.
This condition changes your life. I'm afraid to go to movies, church, concerts as well as a host of other things. During COVID, people in stores would glare at me as I coughed my way up and down the aisles. I'm sure if I hadn't been wearing a mask, I would have been kicked out of the store.
