Can nerve damage from siatica heal on its own from herniated disk ? right foot can stand on heel it drops what kind of doc should i see spine doc?

Weakness: Adam - your sciatic nerve is compressed and you have weakness on dorsiflexion This should be checked right away to see exactly what is happening. Anyone can order an MRI - PMD, Neurosurgeon, Physiatrist, PAin Doctor.

Be evaluated: You would need to be followed closely. But yes, weakness from a herniated disc can potentially improve as the herniation heals. But you need to be followed closely because if it worsens you might need urgent surgery to avoid a complete and permanent "foot drop." See a spinal surgeon to discuss, even if you don't think you need surgery, you need to be followed by a surgeon just in case.
