On Sunday I thought I was coming down with a cold. Figuring it wasn't too bad I went to work and ended up coming home feeling like crap. I developed the typical clogged sinuses, sore throat, and cough I usually get. Here's the kicker: when I get a cold it starts out with a pretty weak case of the clogged sinuses and sore throat and then migrates into a nasty chest cold that takes a while to get over. I knew something was up when when the sore throat stuck and got pretty annoying - that and the clogged sinuses were here to stay as well. A quick trip to the doctor and I was told that I had some kind of nasty allergic reaction which clogged my sinuses, gave me a post nasal drip which in turn caused the sore throat and asthma to act up. She prescribed Astelin, a nasal spray antihistamine and described the allergic reaction as a sort of systemic thing and that the astelin should clear it all up. That was Wednesday. I've been using it as told since then and I've only really noticed a very very slight improvement. Sinuses still suck and the throat hurts unless I'm popping advil. I'm wondering if this is normal and it's gonna take a bit for this to clear up or what. Anyone have any idea how long it should take for this to start to wear off?
Aside from it not being like any kind of cold I've had before there were no fevers or chills or anything like that at any point so I'm kind of inclined to agree with the whole allergy diagnosis (I've always been pretty bad allergywise between asthma and allergies in general but these days they don't bother me so much and if they do 1 or 2 benadryl do the trick)
So is the Astelin preventative or treatment? If it's a system immune system thing going on, you'll have to give your immune system time to recover and fight the current allergy. And then are you supposed to use the nasal spray all of the time?
