The SI blocks are extremely painful. The blocks in the spine are no big deal. Mine did not work, but I have a different dx than you. They put Lidocaine in the syringe to lessen the pain. The most effective way to not allow the little bit of pain to bother you is when they tell you "a little pinch" to begin to take a very slow, very, very deep breathe. It is amaizng how much it helps. Don't worry. The pain is minimal. Hurts less than an IV IMO.
