What you describe sounds more like a bad upper respiratory (nose, throat sinuses) infection that will probably require treatment with an antibiotic. It does not at all suggest an allergic reaction.
If you have not yet seen a doctor for this problem, you should without delay
Oh ya! Use a sinus rinse to help clear it up. Its like when u get a cut, u keep it clean once or twice a day for a faster and better healing. But ya this sinus infection normally last around 10 days but with this wacky weather don't be surprised if once this goes away it may; a lil or a lot; feel like it came back. But with that sinus rinse it also helps u have less of them. Also try zertec d for this. If its really bad or just a regular zertec if not too bad. That's what i also take and is doctor approved. I am 3 and 1/2 months prego just fyi.
Its a sinus infection. I get them a lot. There's blood because u been blowing ur nose either too hard or/and too often. Be careful of that because it can get worse.
