I'm wondering if any of you well-informed PWPs can explain what is causing muscles to become rigid. (One of my main symptoms). I asked my neurologist this, --he said, "good question..." then paused, and said "it has to do with the muscles tensing, and not being able to relax". I suppose this answer should satisfy me, but I feel like I want to understand more about this. Sometimes visualizing something can help. Can any of you offer a fuller explanation? And can anyone offer any alternative remedies? (Besides yoga, exercise, daily stretching, pilates...) Thanks!
