Bleeding spots on the hands may be senile purpura, allergic purpura or drug-induced coagulation abnormalities. It is recommended to go to the hospital for examination, to clarify the cause of the disease, and under the guidance of the doctor for treatment. 1. Elderly purpura: Older people, due to poorer elasticity and increased brittleness of blood vessels, will have bleeding spots when their hands are traumatized (e.g., by infusion and puncture, etc.). 2. Anaphylactic purpura: When people suffer from anaphylactic purpura, it may accumulate to the hands and appear bleeding spots on the hands. Prompt medical treatment is recommended. 3. Drug reaction: When people take drugs that have an effect on blood clotting for a long time (such as aspirin, etc.), it will prolong the time of blood clotting. When the hand is stimulated by trauma and blood vessels rupture, bleeding spots will appear on the surface. When this occurs, medical attention should be sought promptly.
