There are many kinds of SFN, autonomic and PHN. not all of them will show Nerve damage, or inflammation. it could be the part of your brain that processes pain, and other sensations. Or it could be a nerve that is not close to the biopsied area. SIGNals from nearby nerves can transmit to other nerves as pain signals without actually affecting the other nerves.
take tooth paiin,infection for example. Even though 1 tooth is infected the pain is transmitted to that nerve, and the dorsal root, but since the nerves in the head all come to one point, behind the ear, it can easily transmited to other nerves, so you can have pain in the ear, pain in the temple, both lower and upper jaw, and headaches.
