In december, I had something of a cold. Not sure if it was viral or allergies, but I had it. After it had run its course, I continue to have this sensation similar to post nasal drip, but it feels really thick, or even solid. I have a frequent urge to swallow, my throat is frequently dry or mildly sore. Occasionally it feels like there is a small lump in my throat, almost what you'd feel if you had difficulty swallowing a particularly large pill, but as not severe as that.
