I'm currently going through an MEB due to spinal problems. Here is the timeline I dealt/am dealing with on this. I complained about back pain since my first deployment but had that combat arms mentality of suck it up, drink water and drive on. My second deployment it got worse-shots of toradol or robaxin nearly every night jest to fall asleep for three months. Then went to Drill Sergeant school and it still hurt, but I sucked it up. First cycle on the trail-it went out bad. XRay showed some narrowing. The MRI revealed a herniated disk at L5-S1 (AUG 2011). Tried PT/traction and then pain management (epidural steroid injections). The injections worked for a while (7-8 months) but evenutally they did nothing for me. Nerve conduction study showed nothing. Saw a neurosurgeon at a VA hospital after arguing with my PCM about it all. Was not a candidate (SEP 2012) for surgery, but he said that was based off a year old MRI. Convinced PCM to get me a second opinion and a new MRI. OCT 2012 saw a civilian neurosurgeon who said I should have had surgery months ago. Surgery scheduled for one week later. Microdiscectomy/Laminectomy to get the disk off the sciatic nerve and open the spinal canal up some. Two months of con leave. PT started up again in Jan 2013. Med board initiated Mar 7th. New MRI this past Monday revealed the space that the surgeon created has now filled with scar tissue which is why I am still in pain 24/7. Now I am told since I have started the MEB process I can't get another surgery, but that I have to wait the process to be over and go through the VA.
I guess the bottom line is: you are going to be in pain regardless. Just keep on the doctors to get any kind of progress. I didn't get surgery until it was literally unbearable and I even contemplated suicide due to the pain level. I was up to 1200 mg neurontin, 800 mg motrin, and 4 5/500 percosets every 4 hours and it dropped my pain to an 8 from a 10. Spinal injuries suck and you are going to be dealing with it the rest of your life (sorry to tell you that). But definitely try the pain management/PT/Traction first. They all helped in their own way for a while. Good luck.
