Re: Leg and foot feel dead.
There is nothing you can do for yourself at home other than rest and maybe ice or heat. You need to get in to see a spine specialist as soon as possible. It sounds (and I am not a dr!) like you may have a herniation that is putting a great deal of pressure on a nerve; or, you may have an annular tear and the material coming from that torn disc is dripping onto a nerve. If I were betting, tho, I would say it is the former. The longer you wait, the bigger chance of permanent damage. I would guess that the impingement is pretty bad for you to have this much weakness and numbness so quickly.
Please do get some help right away, and then let us know what your dr. tells you...most likely an immediate MRI is in the forecast.
