>>26-27 I ended up just going to my doctor. I didn't go to the ER. The allergic reaction was actually caused by my new dog. I knew that I was allergic to him, as I had been sniffling and sneezing for months. It turns out that the mucus drained all the way through my body, but I was unable to digest it, so it sort of formed clumps and came out. Also, what I thought was blood was just mucus. I was confused, because it was a dark brown color, like how blood looks during the end of your period. I'm on some sort of nasal spray and Allegra D.
