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.
