Spider veins are a milder variation of varicose veins that affect the smaller vessels in the legs. For many people they are simply a cosmetic concern, but for others they can lead to more serious problems. Sometimes spider veins and varicose veins can signal a higher risk of other circulatory issues or be a sign of a problem deeper in the vasculature of the lower extremities. While spider veins are rarely a serious health problem, they can cause significant discomfort in the legs.
Burning and Itching
According to WomensHealth.gov, one of the most common side effects of spider veins is burning and itching in the legs. This discomfort is often caused by the lack of oxygen to the area that was supplied by the spider vein. A lack of oxygen will cause the sensation of burning and itching as the cells do not receive enough nutrients. After treatment this side effect can resolve as the body develops collateral circulation to supply the area.
Pain
According to the American Academy of Dermatology, individuals who suffer from spider veins can have pain that ranges from dull and throbbing to a burning sensation. Physicians have found that the larger vessels are more likely to cause greater amounts of discomfort. However, smaller blue veins have been shown to cause pain to the individual as well. Spider veins are often considered just a cosmetic problem and insurance companies do not pay for treatment. However, in areas where there is a cluster of spider veins, individuals will experience pain and discomfort and will often find that their legs feel better after the veins are treated.
Heaviness and Swelling
Women who suffer from varicose veins and spider veins will also find their legs feel heavy or they have a problem with swelling after having been on their feet during the day, according to WomensHealth.gov. Doctors have found that women who have other family members who suffer from varicose and spider veins will have the same experience themselves. Increasing age, hormonal changes, obesity and lack of movement all contribute to the development of new spider veins. Individuals who already suffer from spider veins and then experience these factors will have a greater risk of developing swelling in the lower extremities and feelings of heaviness.
