Are there any tests necessary for the treatment of spider veins or varicose veins?

I have heard that people get tests done to see if they have spider veins or varicose veins. Is that necessary?

It is not but other doctors still do it and they charge insurance companies for no reason. It is unethical.

I have heard that people get an ultrasound for potential diagnosis purposes. This ultrasound is done with a machine called a duplex scanner, which is a combination of ultrasound and Doppler device that uses sound waves to envision veins underneath the skin. The test is done to see whether or not certain veins have bad valves and whether or not blood is flowing backwards in these veins in hopes of treating these veins as spider veins or varicose veins. To do this on every patient is unethical.

Many doctors think that spider veins can be treated effectively by lasering or using radio frequency on a large feeding vein that may be shown to be incompetent on a duplex scanner. Getting rid of this vein using the newest techniques is expensive and completely unnecessary for the treatment of spider veins and small varicose veins. It is only done as another source of income for doctors who are performing unnecessary tests. Anyone who undergoes a duplex scan for spider veins has not been told the truth and is undergoing a test that is completely unnecessary. If abnormalities are found on that test, some patients are recommended to undergo a much larger, unnecessary procedure to treat their spider veins. This becomes an issue of malpractice.

No one needs a duplex scan unless they have large varicose veins. Patients with spider veins do not need to have that test done at all.
