My Feet Flew Out In Front Of Me On Black

my feet flew out in front of me on black ice porch and fell down 5 steps, turning to my left instinctively to avoid back injury (my father broke his back down steps 13 years ago and i remembered), i landed on all fours in teffific pain but also new no bones were broken... after years of experience i knew i injured my siatic nerve in my left buttock. ive been recovering slowly at home with ice then heat, magnetic therpy and lidocane patches. im able to sit and walk slowly, but unable to lift my leg even a few inches. i m afraid to lay down flat as it was horrible the first time i tried. I know this takes time to heal and i'm carefullly taking it slow. how long and what more can i do
