JDeeziac is right go get a mri and see a neurologist. The numbness is a nerve being damaged and can become permanent if not taken care of properly. I know, I only have 22% of the feeling from my waist down because I ignored my back. You don't want to regret this for the rest of your life. Believe it or not even with damaged nerves the pain can get worse and there is no pain meds that completely help with nerve pain. Best of luck to you. Please get checked soon.

If your symptoms are from a pinched nerve you should have a few tests done such as mri, emg, and nvc to further investigate your problem. A pinched nerve can be quite serious as the damage worsens as more time passes with the nerve being "pinched". Plus having the tingling/numbness and weakness just isnt fun and needs to be addressed much sooner than later. Not to alarm you, but take care of it.
