i have back pain and extreme pain from left bacl all the way down my left leg, i sometimes have to lift my leg manually because the pain is so bad, and it is worse with things like getting inside and out of a car. it takes me hours for the pain to subsude so i can sleep and i am a side sleeper and sleeping on my side is impossible for hours and then i can find a position which i can tolerate, but not always. i wondetr if i have a slipped disk, it does feel like nerve pain but until recently it was on the other side and not nearly as bad as since it has moved to my left side
