I have had lower back pain for a long number of years. I got an MRI on my lower back and I have a disc problem at L5s1. I have pain down the right leg, particularly below the ankle. My right foot turns in at the toes and my foot balance wants to go to the outside of the foot. I walk with a limp and my leg seems to swing outwards at the knee.I walk a lot but feel stiff after exercise and it takes me a while to get going into a normal stride if I stop in mid walk.My surgeon recommends surgery but I don't know how much it will improve me..
