At any point during a migraine my hands (just one or both) will close and I'm not able to relax my hand and keep it open without keeping them pressed flat. It can last 10 minutes or up to an hour and it comes and goes throughout the duration of the migraine. The most important aspect of this is there is no numbness or tingling at all. Everything I've tried to find on this always includes those physical sensations. I would really like to know if anyone else experiences the closing of their hands without numbness or tingling?
