Diagnosed with idiopathic neuropathy in b feet: sensation/motor control are normal; constant tingling without numbness; no trouble at night; feet always ice cold or burning hot. could yrs of tying shoes tightly across high arches cause this?

Although sometimes difficult to uncover, there is always an underlying cause for a polyneuropathy. Your description is confusing, but would wonder about a small fiber neuropathy, which could be evaluated by skin punch biopsies. Shoelace tying was unlikely a contributor. A neurologist with neuromuscular focus might be a good source for further evaluation.

50% of the Peripheral neuropathies are idiopathic or don’t know the cause of the neuropathy. I recommend seeing a neurologist for a work up and diagnosis and treatment.
