I sometimes (several time a week) get a strange feeling in my back when I stand up after sitting or lying down, almost as if a nerve is trapped in my spine. It makes my lower back hurt, brings tears to my eyes and gives me pain in 1 leg which causes me hobble around for a while. If I bend in a certain way, my back will click and the pain disappears (til the next time).
Usually when I get up, I feel my back and hips crunch and I know I will be ok. But, if that doesn't happen, I have the pain. Is it sciatica? Or something else? Or nothing?
