Small Fiber Neuropathy biopsy test results
Last month I had a small fiber neuropathy biopsies of my left leg. Three skin biopsies were taken. One above the outside of my ankle, another near outside of my knee and another at upper outer thigh area.
The ankle and knee area biopsy came back negative but the upper outer thigh area nearer my hip came back positive.
How can I have two negative locations in my left leg for small fiber neuropathy yet the one on the outer side closer to where my thigh joins my hip was positive.?
Can anybody give any insight as to how this can be because I have sharp pains in my feet and pins and needles for 3 years now but the locations near my ankle and my knee were negative but the one nearer my outer thigh near my hip was positive.
