Permanent Nerve Damage from Piriformis Syndrome? - damage to piriformis

I was with a rare neuromuscular disease, or diagnosed with a pyramidal syndrome, and an MRI to see if I could have a lumbar disc. I had sciatica for years and are not treated. You have constant pain because of hip piriformis syndrome. I have another appointment next week. I also sometimes pain and needles in his back leg. And sometimes I feel the pain of the radial nerve in my arm. Would it have permanent nerve damage, sciatica for years is no longer be treated? The pain does not disappear. Remains the same and the medicine is to relieve piriformis to? Suggestions? Thank you!
