this is a very interesting question to me because i love obscure stuff. i should start by saying there often is no answer to "why" for many weird body occurrences. when medicine can't figure out an answer to "why " they call the situation "idiopathic. " this basically means "of unknown origin. " then too sometimes these weird symptoms actually are normal. in your case for instance if your toes have always itched at night then that probably is just normal for you. who knows why? maybe there's something unique about the way the nerves in your toes function. there are certain conditions that can produce the symptom you describe though. one of these is raynaud's phenomenon. in raynaud's blood flow to the fingers toes (and the extremities more generally) is disrupted by exposure to cold temperatures. the vessels go into spasm and the tissue lacks oxygen so it burns or itches or feels painful. a rather obscure symptom of raynaud's is itchy toes. of course if you don't have any other symptoms of raynaud's then it's unlikely this is the cause of your symptoms. another obscure possible cause of your symptoms is gout. usually gout presents with a complaint of sharp pain in the big toe especially at night. gout normally causes swelling too. if you don't have nighttime swelling and redness in the toe then it's unlikely gout is the source of your symptoms. i suggest you continue to monitor the situation and record your symptoms in a log book. even if you just write down the dates and times your toes itch it could be helpful to your doctor in arriving at a diagnosis -- if there is one. like i said many times we have no idea what is causing a benign symptom like itchy toes. wishing you well!
why do just the pads of my toes itch at night? it's mostly the big toe. i have had an emg and don't have neuropathy.
