Hi Evelyn,
It never hurts to check with your physician. But, even after 5 years I cough. Scares my hubby half to death. Certain things trigger the cough:
1) overeating 2) something like vinegar 3) talking while eating 4) just being over-tired and some other things like acid reflux. I did ask the doctor to stretch my esophagus a year ago when the coughing after/while eating got very annoying. They did the stretch, but the surgeon said she didn't think it really needed it. Sometimes I wonder if I get a little virus that causes my throat to swell some. Maybe my symptoms are not anything related to yours, but it comes and goes. Sometimes I can go for several weeks without incident and then all of a sudden I will be bothered for several weeks. I hope you can figure it out.
Oh, I gave my unused meds to my oncologist-radiologist. They would only take unopened absolutely untampered with meds, but mine were very expensive and I hated to throw them out also. I was also able to give unopened cases of liquid nutrition to the clinic. Some of the ones I had didn't even have the cellophane opened on the outside of the boxes. I also had lots and lots of swabs and gauze and bandages and sterile water bottles that I donated to a summer camp. I flushed all the other tablets, but that was before they said not to.
It surely is nice to get rid of all the memories of stuff that was unpleasant.
Best wishes.
