swallowing issues are definitely scary.. mine started with weak lips (unable to purse my lips or make a seal around a straw).. slurry speech too.. but i would choke on everything - solids and liquids.. I couldn't suck through a straw due to lip and throat weakness. and blowing my nose, i couldn't hold the seal in the back of my throat.. so it is really uncomfortable when I would attempt to blow it..
then it feels like my throat is collapsing.. almost like it is resting on my tongue or something.. when i was at my worst, the sound of my voice could hardly make it out past this "collapsed" portion, it was muffled and very nasally... throaty? just awful.. when I start to get sick, i feel pretty fatigued for a couple of days before, but also notice my nasally voice and swallowing get funny.. it's a warning sign for me!
