Hello,
With the question “Is it serious to have a lot of blue veins in the legs? ", the doctor would like to answer as follows:
Blue veins in the legs may be due to the superficial venous system and may be accompanied by signs of varicose veins. This is one of the signs of lower extremity venous insufficiency. However, the presence of blue veins alone as you describe is not enough to make a diagnosis. Symptoms of lower extremity venous insufficiency are usually calf pain when standing for a long time, sometimes with foot edema, paresthesia, frequent cramps at night,...
To diagnose the cause of many blue tendons in the legs You need to schedule an appointment with a Cardiologist for a clinical examination, doppler echocardiography from which to diagnose and treat if indicated.
If you still have questions about blue veins in your legs, you can go to a hospital under Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
