Neurogenic Claudication After Spinal Fusion



I had severe lower right side back pain and leg weakness when standing and walking (worse when standing). When I would sit down, the pain and weakness would go away quickly. I had two herniated discs with nerve compression and spinal stenosis.

I had fusion surgery two months ago for my lower lumbar spine. While initially I felt a little bit better, now that I have stepped up walking again, I seem to have pre-surgical symptoms.

I`ve been told that the nerves may need time to heal and the fusion to fuse. I am curious about why this is the case -- I understand the nerves might take time to heal -- but why would they be affected by my standing and walking vs. sitting, assuming the fusion corrected the stenosis issue? And why would the healing of the fusion affect pain and strength levels at this point.

I`ve also been told that this might be scar tissue and this might account for why it seemed better and then got worse.

Thank you.
