Why do you have a bruise that is shiny and smooth that wont go away?

A shiny, smooth bruise that won't go away could indicate several underlying issues. It may be a sign of a hematoma, where blood collects under the skin, or possibly a vascular issue affecting blood flow. If the bruise persists or is accompanied by pain, swelling, or other symptoms, it's important to consult a healthcare professional for proper evaluation and diagnosis.
