It feels as though I have slimy stuff stuck in my throat, and when I try to huff and cough it up, it won't come up. I can't swallow it either. Sometimes if there is a large amount, it makes me heave. Occasionally that will shift it, but not always. I've tried having a drink of water, gargling, oral spray, but nothing seems to work. Does anyone have any suggestion? Thank you in anticipation.
