Hey erica, I have the same problem and have had it going on 2 years now. I was tested for asthma, which came back negative, they gave me the inhaler anyways, but it doesn't help. They gave me prevacid for gerd, which was great for the hearburn, but didn't touch this. They had me do a nuclear stress test, which came back normal. They checked my blood for abnormal thickness and for polycythemia vera (sp?) which came back negative. One thing i've noticed with my problems is my position when sleeping, if I lay on my back or left side, they seem to kick in with a vengance, if I lay on my right side, I can at least fall asleep. I read on another forum dealing with this, that one guy tried this stuff called bronkaid, which seemed to help him. I've yet to find it in a store where I live though, so I may just order it online (which I just did with the salt inhaler) i'll let you know how it turns out. This has to be the most frustrating illness i've ever had, due to the uncomfort, inconvenience and the inability of physicians to help. I'm pretty sure it's not life threateningor anything, but man is it a pain. Have you noticed any increase in the amount of mucus in your lungs since it started? I seem to have an increase. My problems actually started with a strange cough I got when I went to hawaii for my honeymoon, if I sat there with my mouth open it sounded like pop rocks. I was treated with antibiotics, and it went away. About a week later is when this all started. I thought about asking the doc for something that is supposed to break up congestion in the lungs, ill probably do that next visit. What are the specifics on when your problems started, anything strange happen at that time? Sorry if these are personal questions, I just want to get to the bottom of this and be done with it.
