Thanks for the feedback. I have felt movement still, over the last day since I wrote this, in the same area, up and down, almost to my tongue and back down again. It makes me wonder if they are going to come up and out, which is something I really dread.
I have had such a feeling of apprehension and like something big is coming, it's very odd. It isn't a normal feeling for me, but I half wonder if it's coming from the parasites themselves. Now that's an odd thought!
