I have had two Medial Branch Blocks (MBB) done on 10/29/14 & 11/06/14 on L3, L4 and L5.
I have experienced my pain going from a 7 to 3-4, five days after my first MBB.
My first MBB: was very helpful (it felt like the results I used to get with caudal injections). Bupivacaine (long lasting relief) medication was used, I had relief for 8hrs. I noticed my left leg, from the knee down to my ankle has been numb since my first MBB.
My 2nd MBB: the procedure was very painful, I had to be re-numbed up half way through the procedure (I was told I most likely was tender from the first MBB done the week before, I had a different radiologist perform my 2nd MBB). Lidocaine was used (short lasting relief), I had relief for 2hrs.
Based on the good results I had from both MBB's, I'm scheduled to have RFA next Monday 11/17/14. I will take a valium an hour before the procedure. This will be my first round of RFA (I'll be awake for the procedure). Im a bit nervous about getting it done.
I have had ongoing relief since my first MBB, I asked my PM doctor if I should follow through with the RFA, he said some people experience a phenomenon of pain relief after a MBB's, the relief will go away and I will experience pain again. I must say, I have not over exerted myself since my MBB's, I haven't gone shopping or done much of anything for fear of the pain returning.
Has anyone else experience less pain weeks after a Medial Branch Blocks? Has anyone lost strength in their leg after lumbar RFA? Any advice for a newbie about to have their first RFA?
