Do you want to mitigate those veins on leg? While it is true that these may not be necessarily dangerous, many times they can become painful. That not withstanding, these visible veins can look unattractive to many.
These veins are generally defined as varicose veins. As such their removal might be covered by your health insurance. So there is no reason not to attempt to do something about them.
You may have concerns of how removal of these veins may affect you. First off you generally will not need time off from work. Likewise you are not at all bed ridden. In fact it is advised that you keep moving. Todays procedures do not require vein stripping surgery. The procedure is minimally invasive.
I have seen women who have developed varicose veins and spider veins. I have spoken to women who seemed more concerned about them than they do about their weight. I have seen the results from these procedures and they are astounding. You should consider it for health reasons and aesthetic reasons. It is something that will provide satisfaction.
