I have some issue happening in the back of my throat. I dont know what it is, and it only became an issue recently. It's like a mucus, but not in my nose, so I cant blow it in or out. However, it has an effect if I hack it back. It must be pretty thick because it causes me to become nautious if I try to eliminate it, and has tendancy to make it difficult to swallow. I've had flu symptoms before, but this feels different. (This has been pretty consistent for the last month or two.)
