Varicose or spider veins are the commonest veins issues among people. If you are one of them, you may also need to go through an ultrasound test to have a proper diagnosis. You can ask your doctor, what is the treatment for varicose veins? Luckily there are less invasive procedures to treat varicose veins and can be conducted on an outpatient basis. The most recommended treatment is Sclerotherapy. Your doctor will inject a solution or foam to make the diseased veins collapse and fade away.
