My big toe goes numb sometimes in the past 2 weeks and my some fingers get really cold while others are really warm. whats going on?

Circulation problem?: It could be signs of poor circulation. See your physician to have your circulation evaluated to prevent potential complications.

See a doctor: The two problems could even be unrelated/coincidental. Numbness can be caused by a pinched nerve, nerve damage, and even poor circulation. See your doctor and also ask about raynaud's disease/phenomenon which is spasm of the blood vessels in the fingers and toes illicited by exposure to cold.
