You are the patient. You have the right to say no.

Just a reminder. You can decide not to do the block. If you don't feel it is helping, if you feel it is too scary, whatever, you can say no.

As for gabapentin, the top out dosage is around 3000 mg in a day, so you have room to go up if your doctor will approve it. You might say to him you need the more immediate relief right now, and the block doesn't seem to be providing that.

As the patient, your pain needs to be addressed. And I am speaking as one who (as I said in another thread) REALLY doesn't like to change two things at once because you won't know what is doing what. Doctor is trying to address the pain thru the blocks, you have to decide if that is worth it or not.
