Can somebody tell me if this is nerve related pain or visceral. I have been suffering constant deep dull pain 4-5 level in right abdomen and flank area after keyhole kidney surgery 4 months ago.My doctors saying they can't tell if its surgery pain, nerve and tissues healing or if its kidney hurting.
Some people are saying if its nerve pain, it is always there and can be burning type. My pain never goes away and sometimes I feel burning sensation to it.
And then I hear since its very deep and vague diffused throughout my right side and feels heavy in flank area( which is associated with kidney) that it must be kidney related and not nerve.

I tried gabapentin which does not help at all. Nsaids dont help pain at all also. Only percocept helps, so is it not nerves then since pain would be helped by gabapentin more? How can I rule out since no doctor want to tell for sure. Thanks
