Hand specialist: You may have a blood vessel that goes into painful spasm on exposure to cold or trauma, but a hand surgeon could check the bones and joints of the finger for you.

Glomus tumor: Symptoms sound typical of a glomus tumor. A benign tumor of the neuromyoarterial plexus of the finger most commonly located in the nail bed. Classically gives rise to severe pain with exposure to the cold.
