Firstly thanks to Dr. Mark and all who have posted on this subject, especially CACIMX622. Here's my situation. Mid March of this year I went on a 10 mile run. (12 min miles-SLOW) Felt great but the next day tripped in the yard holding a kids carseat over my head, fell on my lower back, and couldn't get my arms or hands behind me. Two days later major pain, brutal sciatica in my left leg, felt like someone was hitting me in the upper part of my butt with a baseball bat. For the next 6-8 weeks I got no more than 3 hours of sleep at a time if I was lucky. I couldn't sit for more than 5 minutes, I would walk outside at 3am-4am to lessen the pain. Went the route of chiropracter, orthopedist, MRI. 2 herniated discs, L4-L5, L5-S1, and cant walk on my left heel. Orthopedist, 2 orthopedic surgeons, and neurosurgeon all say I need surgery to fix the herniated discs in order to correct the foot drop. All through this obviously no motocross, not even the sand track, but I was following the forum and doing exactly what Dr. Mark and CACIMX622 recommended. Lots of cardio, walking, inversion table - the whole bit. Anyway, my back pain and sciatica are just about gone, (except when I spend alot of time in the car) but I haven't ridden or jogged yet. The foot drop is not that big of a deal to me, I have no problem doing the eliptical, biking etc. Question is, the surgeons tell me that foot drop can lead to other problems and the longer I wait, the less benefit I will get from surgery.(classic surgeon's response) Should I stick with the workout routine, or go under the knife? I still don't know if I will be able to ride and would like to wait another 8-12 weeks, but I am not afraid of the blade if it will help. Once again thanks everyone for posting, sorry about the long post. Lets see if Bubba can survive all 12 rounds.
