My husband had ingrown toe nails removed in 2002. He knew right away something was very wrong. He has not had a pain free day since. It has traveled up both legs to right above his knees and last year showed up in his hands and is trying to continue into his arms. He was 47 years old. The doctor that did the toe nail removal did not recognize the symptoms at the follow up appointment one week after surgery. Nor did he suspect anything after 2 phone calls over the next 2 weeks complaining of the classic systoms of RSD. I diagnosed it myself from researching on line before going to a neurologist. He asked whom had diagnosed RSD and we said i did and he said "it isn't RSD it is PN". His ego wouldn't allow me to be correct. We did go to another neurologist at an University Hospital who concerred with my diagnosis. However no treatment received for 16 months after initial toe nail removal. This has been a very long nasty nightmare ever since.
