Symptoms of Hemangioma
Hemangiomas are usually painless, red to blue colored lesions on the skin, lips, or inside the mouth. They are often soft to the touch. Most often they are flush with the skin or slightly elevated, but sometimes they grow from a stalk. Superficial lesions may bleed or turn into sores, particularly if bumped or injured.

Deep hemangiomas in muscle may cause pain, as well as swelling around the hemangioma that increases with activity.

Hemangiomas in bones may cause pain and enlargement of the bone.
