Same symptoms here, guys. I started experiencing tightness in my airways and mild wheezing last fall. The symptoms grew worse over a period of a few months, started improving in January and returned full force last month. I feel pretty good in the morning but get worse over the course of the day but I sleep well (which suggests it isn't asthma). Eating triggers several hours of discomfort so I am reluctant to eat now and have lost weight. I have the skin thing going on too. I get small red patches kind of like hives throughout the day in response to washing my hands, touching something, etc. They don't itch and they disappear in an hour. I started taking zyrtec which has helped with the skin part but not the breathing.
My doctor is convinced it's anxiety but like Gina, I'm so worried there's something more sinister going on. I had blood work, a pulmonary function test and chest xray last year which were normal, no other tests. I hope it's anxiety because if it is, I am hopeful I can learn to manage it.
