Well, I promised to update on my coughing issue. I still have this terrible cough every 20 seconds

If I don't cough the preassure in my chest builds up and I need to.I went to pulmologist who took the spirometry test and my exhale was normal, he told me (80% of air exhaled in first second). I am 92% of my age/weight group which is considered normal as I have sedetary job.I told him my cough made my chest in such pain I can hardly stand up from yesterday. But he told me I have to take anothr xray as he hasn't seen the first one and I have to take asthma test, but he believes I don't have asthma, but a postnasal drip because my nose divider is broken (but it is broken to one side since I remember) or that I may have GERD problems. But I sure do not feel any heartburn, when I had stomach problems years back I didn't cough!Now this kind of things get me scared, it is always same pattern. Nobody seems to be able to find what is wrong with me and after a while I go to doctor and he seems clueless. I mean, I can not cough so much of a postnasal drip and why would I got it so suddenly and can not get rid of it with anything he advised me to do?!It is THEN I start obsessing I have something bad. I mean, my voice seems changed and I have read in a brochure by the doctor that I may have swallowing problems and I am unable to swallow mucus that is normal very vell and I have problems. This is listed as one of the reasons in the brochure. Yes, the neuromuscular bulbar weakness

I mean, some people can not swallow in this forum and think of bulbar, I may think of bulbar because I cough. And I may cough because I can not swallow right any more, my tongue has such a bad tremor

I may be over the edge here but really, if the doctor could find out what is wrong that I cough so much (and it is not only iritating, it is devastating how much I cough, I can not work, sleep etc.) and give me explanation I would not worry... But he clearly can not find why I cough and he says it is not a lung problem at all in his opinion (he waits for image to confirms this). Well, of course a pulmologist won't even think I may have bulbar ALS now, would he

The only hope I got was that I can cough much, means my muscles in chest are strong, but last 2 days I am mostly barking as I can not inhale much because my chest is in such pain because of coughing so much...Now am I completely mad or can ALS really show it this way with coughing because of the swallowing issues? And I noticed first at skiing and now at home, I have hard time pronouncing some letters, like "ch" (š). My wife doesn't even notice this. I really don't know what to do. I still twitch, but at this moment I don't even care, I have a headache because of this cough and it is the most wierd cough I ever had. And doesn't get any better. If this is some bulbar weakening it even won't. I just hope I am wrong in this. I just wish someone would give me some explanation at doctor's... I cough enough to almost throw up or choke. Coughing up clear mucus btw. all the time. Maybe I can not swallow it ok?!
