Pain in the butt going down my legs. Now my legs r going numb , just if I drive my new car. Feel like I've been sitting Indian style or sitting on steel all day. The pain is breath taking
Sounds like you have a pinched Sciatic nerve which if it is then you need to see your doctor for it - URGENTLY. Get some muscle relaxants, chiro and/or massage therapy and tiger balm on the spot to help ease the muscle and nerves.
Good luck and hope this helps
