I'm still having some significant pain. At the highest its a 6 and lowest is a 2. I also had the epidural shot 7n my left SI this past Monday and sadly it didn't work. I see my surgeon for my 3 month follow up in 2 weeks so im anxious to see what he says. If this ALIF(L4/L5) doesnt help im strongly considering the neurostimulator implant. Does anyone on herr have one? What are the pros/cons as compared to the external tens units?
