Yep i had it for about 2 years and my doctor told me that its sorta all in my mind the swelling up of my throat. I used to get it really bad and i thought i had glandular fever but my tests came back negative. She also thought i had a minor case of thrush in my throat!
So what i did was, after i used any medication or puffers for asthma i make sure that i drink some water or at least rinse my throat after i use it. And if i start feeling my throat or glands swelling up, i just concentrate on my breathing and relax! I still get horrible post nasal drip though. Cant get rid of that
