Top of left foot and toes partially numb / tingling for over a year and diagnosed with possible peroneal nerve damage (all other blood tests good). Did a home pedicure last night and woke up with all my toes and ball of foot extremely numb on same foot (affected the bottom this time). Could this be something else?
I am sorry for your issues you're experiencing. Judging from your description it doesn't look indeed like the perineal nerve distribution. While nerve territories are not always clear-cut, that area is usually related to damage to the tibial or sciatic nerve. Of course a clinical neuronal would help to assess motor involvement, along with tests like ENG (similar tests to what you must have already undergone for your perineal nerve damage). Hope you will get better soon. Don't hesitate to write for further inquiries.
