Hi,
I'm so sorry that you have that. It sounds awful. I have an invisible rubber band around my foot but that's nothing. I can't imagine how annoying it would be around my neck :/
I have constant squeezing around my waist too. I'm really looking forward to that going. I hope your neck band goes away soon! Have you tried visualising it "falling off on the floor" I find those sort of things help me when my waist is tightening up. Sing Let it Go and picture it falling off
