A couple of hours ago my throat started getting really dry no matter how many drinks I had it has now got to the point where I am having difficulty swallowing. I can talk but it feels like someone is squeezing my throat, my arms and leg muscles are also really aching and heavy. I was diagnosed with hypothyroid a couple of days ago and started taking tablets for it. I am a healthy weight 128 pounds and 5" 9, really don't know what to do.
