May be cellulitis. Besure to have it seem by a doctor. The splinter could have carried an infection into the finger and now it has spread to the whole hand. In the mean time, warm compressed and draining any puss at the splinter site. And remove the splinter if you havent done so yet.

Sounds like Raynauds. It sounds like you may have a reaction to cold called Raynauds phenomenon. It describe it to people as an "allergy" to cold.
