I would just like to begin by saying that I haven't always had this problem. It started about 2 weeks ago. I just woke up one morning and wasn't able to breathe out of one side of my nose. It switches every once in a while but one side of my nose is always blocked. I've been to an ENT doctor and he told me that it was either a virus or allergies. The ENT doctor told me if it lasted over 7 to 10 days then it probably wasn't a virus. He put me on meds for allergies and they aren't really working. I've tried Veramyst, Xyzal, Claritin, Maxifed, and Sudafed. Sudafed felt like it was helping a tiny bit at first but isn't anymore. I'm also taking Singulair to help me breathe at night, but I don't think that's helping either. Also, I don't know if this might be what's wrong but my ENT doctor told me my septum was C-shaped.

I started taking Benadryl recently and at first it opened me up pretty good. It's not really helping me now, is that normal? It seems all the allergy meds I've tried helps a little at first then stops. Even when they do help me breathe better it still seems like something is still blocked on one side of my nose. When this first started the only problem I was experiencing was just one side of my nose was blocked. Now I feel pressure below my eyes, behind my ears, and even on the bridge of my nose sometimes. I've noticed when I blow my nose there's a little bit of blood on the tissue. The worst one of them all is when I stand up after I've woken up or sat down for a while, I'll get really dizzy and everything goes black for a minute.

Any help would be very appreciated. It's a bit hard to sleep and concentrate because I can't breathe too good anymore.
