Had a full body EMG at end of July which was surprisingly all normal but my symptoms persisted and has progressed. I don't have any true cramps, but my throat and tongue feel constant stiffness/strain as if I am being choked by my own muscle, and swallow feels weak. I went from 57kg to 54kg in the last three weeks which is terrifying. Probably will get an EMG a few weeks to see what is going on.
