A diagnostic test is the first step. During this initial evaluation, you will likely undergo a specific ultrasound test referred to as a “venous reflux study” that will evaluate the quality of the valves in your veins.

Compression stockings, which you can buy in most pharmacies or medical supply stores, are specialized socks or hosiery intended to improve blood flow by compressing or squeezing the legs. Compression stockings may help alleviate physical discomfort caused by varicose veins, although they shouldn't be expected to “cure” the enlarged veins. 
Compression stockings are not safe for everyone. Talk to your doctor first before trying a pair yourself.

In addition to other treatment options recommended by your health care provider, there are a variety of self-care strategies that will help you manage your varicose veins and potentially prevent more from developing. You can:

• Maintain a healthy weight
• Participate in regular exercise
• Adjust your position more frequently while sitting or standing
• Eat a healthy diet, especially one lower in salt and high in fiber
• Avoid wearing high heels and clothes that fight tightly around the waist and groin (which may impair blood flow)
• Elevate your legs while sitting or lying down
