Suggest Treatment For Shortness Of Breath And Chronic Dry Cough

I have had a chronic cough for 28 years. Dry and productive. It is set off by wind, talking, after eating, air temp too cool or too hot, talking on a phone, etc. I have had all testing and diagnoised with Laryagospasm Spamadic Dysphonia. I also believe I have allergies that contribute to it. Now, since my colonoscopy under Propofol, I now have PVC s, along with a jumpy feeling in my upper stomach. Usually set off after eating or resting. Although sometimes it is non stop. I had a cardiac treatmill w/echocardiogram and all was fine. My dad had his 1st heart attack at 57 & I am now 58.(Female). Donnatol did help the jumpy stomach and calmed the PVC s but not taking now. I also sometimes, have alittle shortness of breath when I lay down in bed, or brush my teeth, towel dry from shower, etc. Valium sometimes will help. I also have an elevated HS CRP. The cardiologist doesn t seem to think I need to worry about anything. Any ideas of what I can do or take to help any of the above issues. Somehow, I feel that they are all linked together! Janice
