No seriously,
I'd first ask you if you notice that it happens certain times. (e.g., when you go out drinking all night the night before)
Do you drink, do you smoke?
There are a few things to think of, but I need more of a history from you before I can really give you an answer.
Since
you are in the military, I'll guess it's not drug related. If you
weren't I'd say "Edema of the uvula together with bronchitis, asthma,
and rhinopharyngitis, suggests inhalational injury, often from
recreational drug use (e.g., recent heavy smoking of marijuana, crack
cocaine, hashish)."
In your case though, it can also be
idiopathic or associated with drugs such as NSAIDs (ibuprofen, asprin)
or ACE inhibitors (heart drugs). If it is an isolated finding, and
symptoms are uncomfortable to you, dexamethasone, 4 mg, can help.
Hope you get some good
