I was told that I have a deformity of extra bone at the L5, that my nerve endings are moving over it. Not real sure of anything else as I went a short while after the death of my younger sister in hospice at my home. I first experienced my feet when taking of tennis shoes , my feet would feel like they were asleep without tingling...then my upper right leg after shopping became numb like I had a shot at the dentist office. I left his office, hearing what I typed above and asked if I needed surgery, he said no I think. I have not been back, this has been over a 4 yr period and now when sitting my feet are feeling as if they go to sleep, I get up start walking and they wake up. Can you give me any idea what is wrong with me?
You have arthritis of the spine and the nerve is getting irritated as it leaves causing thigh/calf/foot cramping and numbness.  In the positions where it you don't feel it the compression is less severe, so the nerve can work normally
