900+ hrs Anvis 6/9's.
After longer NVG flights (3-6 hrs) will have a "tightness" between my upper shoulder blades. Usually get my wife to give me a big bear hug squeeze while slightly lifting me up which pops about 4 vertebrae in my upper back. Problem solved. Ready for another NVG flight...
Not sure what I'll do when she can't lift me anymore
