Red spots on the hands without pain or itching may be caused by dilated capillaries on the hands, capillary naevi, and lowered platelets. Treatment is generally general treatment, drug treatment and so on.
1. Capillary dilatation of the hand: If the hand is exposed to high temperature, ultraviolet radiation or topical hormonal ointment, it may cause local capillary dilatation and red spots, generally no treatment is needed, and it can be recovered on its own after adjusting the environment or discontinuing the use of medication.
2. Capillary nevus of hand: manifested as red, clear boundary and smooth surface spots on hand. Generally there is no need to do special treatment. If the treatment can take strong pulse laser treatment.
3. Reduced platelets: It may be caused by decreased blood clotting function due to reduced platelet count, which leads to localized bleeding spots. The cause of thrombocytopenia should be identified (e.g. chemical drugs, electric radiation, radiation, etc.), and exposure to these factors should be avoided, and generally no special treatment is required.
If the above symptoms occur, it is recommended to go to the hospital in time to identify the cause of the disease and give targeted treatment.
