I just had a discectomy on my L5-S1 disc in October with an Orthopedic surgeon. He had me do an MRI of my back Dec 31st because I am still in a lot of pain. I saw him last week, and he told me that the MRI didn't show anything, and that it is all psychological. So, I went to my family Dr. today and he told me that I have neuritis and scar tissue on the nerve. What is neuritis, and is there treatment for it? Also, is scar tissue bad? I really want to change doctors and get a second opinion, maybe see a neurologist?
