I'm so mad... Was brushing my teeth & it was some phlegm in the back of my tongue so I feel it every time I put my tongue back in & I'm not giving up until its out so as in doing that I hear a pop & feel a pop in my back by my butt & then it was a dull pain there NOW it hurts to sit & get up!!!!!!!!!!! What do I do? How long does it stay? Anyone have this happen before?
