Nearly a month ago I had my second microD, this one at L4/5 last year L3/4. I have Foot Drop with a manual muscle test (MMT) grade of 1. After physiotherapy or other activities I can get a warm, electrical sensation with increased pins, tingling and numbness down from my Sciatic nerve to the Tibialis anterior all the way to the big toe. This is the same sensation that originally caused the Foot Drop pre-operatively but to a lesser degree. ( I had emergency surgery 24 hours after disk rupture and foot drop first manifested). The numbness is so severe I can hardly move my big toe whereas before I wiggle my toes. Either way I can't dorsiflex my ankle or toes. After awhile this pain and numbness subsides and I return to post-operative baseline. I also have occasional lumbar pain and weakness. This has caused me to suspend PT and I've been on complete bed rest (as opposed to 90% bed rest). I know time will be my greatest ally but I want to do everything possible to facilitate a complete recovery of my dorsiflexion.
My questions are as follows.
Will complete bed rest jeopardize restoration of the nerves? I'm told that increased blood flow and core strengthening is essential to a complete recovery.
How long does it typically take for the annulus fibrosus to heal? In the interim is it possible for additional Nucleus pulposus to leak out and be causing the symptoms referred to above? If so, is this the definition of re-herniation? Or is this just typical lumbar Radiculopathy ? I want to avoid a multi-level fusion.
Don't worry I'm consulting my docs but want other perspectives as well.
