Red_34....sounds exactly the same thing with the leg giving out on me. It does seem like nerve pain as it's so sudden and sharp....kind of when you get that feeling in your mouth but it's down my bottom. And it's so sharp that my leg cannot hold my weight.
kazbern, thank you so much for both your responses. Gonna look up prioformis syndrome. Is this something that physio therapy could help? I'm so scared of doing stuff as to irritate things more.
