Possibilities: This could be from trauma (like bruising), vascular compromise (diminished blood flow), damaged nerves, or more specific conditions like raynaud's (usually associated with autoimmune diseases). Talk to your primary care physician first and a referral will most likely follow based on his/her findings.
