Hi, I had a Micro D and laminectomy 7 months ago for l5s1 herniation with bone fragment the size of thumb nail under the nerve root. Radiculopathy still present and pain level is a 7. I am currently on 2400mg a day neurotin and baclofen 3 times daily and lortab. at 5months post op my neurosurgeon had me do a series of three selective nerve blocks at l5 they were done 2 weeks apart I have constant back pain and sciatica down my left leg a hips ache very bad even with the nerve blocks they did not help. My surgeon did another mri at 2 months post op and states that my nerves were very inflamed but he did not see a re herniation. would this be considered a failed back surgery.
