Peroneal neuropathy. Until my injury.

I injured my back in 2014. L4,L5 and S1 disc compressing my sciatica nerve. This caused many mobility problems as well as radiating pain down my butt, leg and into my feet. I have had two discectomies. First surgery was L4 with minimal relief and i also sneezed a week after surgey and all my pain came back and worse. I also then had the pain that went down my butt and leg into the back of my knee and my ankle. My second surgery was L5 and S1 with significant relief, but still having some pain and now pins and needles in my right foot as well. My first neurologist diagnosed me with peroneal neuropathy from compression from my l5 and s1 disc herniation on my sciatica nerve for so long. My new neurologist told me my neuropathy has nothing to do with my back and told me the peroneal nerve is in the ankle... I'm so confused because this is not what my first neurologist told me and I feel it has to be coming from my back since I have never had any symptoms or problems until my injury.
