Can i have neuropathy even though the skin biopsies done on thigh/ankle/calf were negative for "peripheral neuropathy" bc my feet still tingle/feelhot?

Distal polyneuropath: Skin biopsy is useful for detection of peripheral neuropathy predominantly affecting small unmyelinated nerve fibers, likley ruled out in your case. Depending on the clinical presentation, nerve & possibly muscle biopsy are needed. Emg/ncv, MRI (cns/spine), labs including blood and CSF serologic studies, & consultation w/ neuro & int med/rheum.
