I am 45 yrs old and i hav spider vein in my right leg ? kindly advice what to do?

Nothing: Spider veins are cosmetic, and are not necessary to be treated. Many treatment options are available, including saline injection, laser, etc.

Several options: There are many ways to treat varicose veins including sclerotherapy (injections of various chemicals) and laser. Choices are based on the underlying cause and severity of the problem. Best bet is to see a vascular surgeon, plastic surgeon or dermatologist for a formal evaluation.

See a specialist: Your problem is treatable. A phlebologist - a vein specialist - can tell you the right treatment option for having the vein removed. Most treatments last about an hour and are done under local anesthesia. Phlebology.Org for referrals.

Vein evaluation.: If you have a few spider veins then sclerotherapy would be the treatment of choice. If you have many spider veins then you should consider having a venous evaluation with a venous reflux ultrasound to see if you have underlying reflux (leaking vein valves) which may be the cause of the spiders. A vein specialist would be able to evaluate you.
