Long term low back and right leg sciatica. MRI shows DDD and disc tear at L5-s1
Yesterday I had a L4-5 discogram and L5-s1 disc block. The L4-5 disc was found to be normal (as expected). I still have pain in low back and right leg. Does this mean that the L5-S1 disc block has not worked or will it take some time?
Would appreciate any advice from anyone who has had a disc block.
My Surgeon is proposing a TLIF but if the block doesn't work I'm unsure if the TLIF would work also.
