That could be what is called thrush. It is an infection in your throat. If you take a flashlight and look there might be white things on your throat which will require a medication to get rid off. I had a horrible problem with thrush and had to be put on the HFA Adviar. Another side effect is actually worse asthma attacks (which is why advair is a black label drug) which can cause death. I have noticed that since going on it, my attacks have gotten worse but i fear actually going off of it.
I have been on Advair for a few years, but I am horrible at taking medications with any consistency. A few months ago I started to take my Advair religiously. I have gained 7 pounds in as many weeks (I am usually very thin and my weight has not changed in 10 years, even after two pregnancies). About a month ago I also began feeling an uncomfortable lumplike feeling in my throat, not painful, just annoying. I don't know if these "symptoms" are linked to the Advair but I am going to stop it for now and see what happens....
