Bilateral carpal tunnel and tarsal tunnel can be a sign of a hereditary neuropathy. Charcot Marie Tooth (CMT) causes both large and small fiber neuropathy as it advances, particularly the axonal or type 2 variants. It took my podiatrist to put my numb feet and ankles together with an old diagnosis of bilateral carpal tunnel and send me to a neurologist who did an EMG/NCS on both arms and legs and sent me for further testing and a skin biopsy at John Hopkins.

Does anyone in your family have neuropathy symptoms? It can be quite severe at a young age or very mild in late middle age and be the same condition.
