Cause: Chronic irritation of the nail from rubbing in shoes or direct trauma to the nail.
Appearance: Dark red/blue/purple toenail, blood under the nail, loose nail.
Treatment: Early evaluation to rule out a broken bone. Evacuation of blood performed with sterile instruments followed by antibiotic ointment and bandage with or without removal of a portion or the whole nail.
Long-term prognosis: Nail can become thickened if the nail root is involved. If the bone underneath is broken this is an emergent situation that should be under the care of a doctor immediately.
Who to call: Podiatrist.
