### Human:\nafter being sick i feel like i have hair stuck in my throat and i have a tiny knot under my chin. what could this be? . ii was sick 4 weeks ago with cold/sinus issues but it cleared up. i feel like i constantly have to clear my throat and brush my teeth. nothing makes the feeling in the back of my throat go away.\n\n### Assistant: could be an allergic reaction to something. maybe a medicine you've been taking. hair in your throat feeling. do you have pets in your home at all. if so you may really have a piece of hair in your throat. i have before and took some time before it came out. i can not take zyrtec makes my allergies worse. some things to think about. dry mouth try salt water. not really sure just some ideas to throw out there.
