L5-S1 spinal disk question?

I had a Mri on my back last month. I am a 36 yr old male, healthy. Had an Acl repair in 93 that causes knee pains. dr 1st order'd Mri's on both. My lower back Mri showed degenerative disc disease at L1-L2 and L5-S1 with foraminal stenosis at L5-S1 disc space and minimal neural impingment. Can this be the cause of pain in my right ok and right thigh? I know my right leg and hip hurt, just trying to understand. Dr. didnt really explain, have a follow up saturday.
