What Causes Sweating In The Toes?

I am a fairly healthy semi active 48 year old female. I am hypo thyroid controlled with armor. I smoke about 10-15 cigarette a day. 5 8 1/2 , 147 pounds. For the past couple of weeks, my big toe on my right foot feels wet. Doesn t matter if I am wearing shoes, socks, or barefoot. This has happening multiple times thought the day. Should I be concerned?
