I had a posterior fusion at l5 s1 back is September. I have done really well. Back to work in 5 weeks and out of the brace at 8 weeks. I went off pain path in March and pain pills in April. I was told I was completely fused in April at 7 months post op. I recently though started having leg pain down my right leg and some toe numbness. This isn't as bad as pre surgery which the pain was always 10. But I would say that I have been having 7-8 out of 10 pain. Is this normal? Should I check back in with my doctor? I have also noticed some leg weakness on this side. Just worried I am headed down the same road as before. Can the l4 l5 disc cause the same pain?
