Yes Valsalva aggravates me, makes me lightheaded. As far as flying, so far this year I have been on 82 flights. I didnt know why but I felt my neck/shoulders hurt worse on the flights, I just attributed it to the uncomfortable seats. Sometimes I become aggitated like I want to be off the plane. Sometimes I get a little dizzy, when I cant ground myself. Im always trying to stretch my neck, I find myself tilting my head without even being aware of it, especially to the right. Is Beth’s post on this forum, if so I will look it up.
