If you have tiny red dots on your arm, it could be a condition called “petechiae,”
which are small spots of bleeding under the skin caused by broken blood vessels,
and could indicate a range of potential issues from a minor injury to a more serious
medical condition, so it’s best to consult a doctor to determine the cause and appropriate treatment.
Key points about petechiae: Appearance: Tiny, flat, red, purple, or brown dots
that don’t blanch (don’t fade when pressed). Causes: Minor causes: Strenuous activity,
coughing hard, tight clothing, injury to the skin More serious causes: Infections
(like meningitis), blood clotting disorders, low platelet count, certain medications, leukemia
