I reherniated the same disc, l5,s1, 8 months after a microdiscectomy, and now have a lot of pain in my left leg and glute after sleeping. what do i do?

Varies : Approximately 80-90 percent of herniations will heal over time, even in patients with previous surgery. Choices would essentially be the same as before you had surgery: give time with possibly use of medications, or do noninvasive treatments to see if they will help (therapy, chiropractic, traction, modalities), or do interventional procedures such as esi, or consider more surgery.
