In adults, there are many different conditions that can affect the legs. In younger adults, the most common problems are simple bug bites and allergic contact dermatitis, such as that from poison ivy. Occasionally, large allergic rashes (eg hives, urticaria) will affect the legs. Chronic conditions such as psoriasis and eczema can also affect the legs. Older adults will often have trouble with the blood vessels in the legs. Varicose veins are caused by a failure of the superficial veins to empty properly. When the deeper veins become compromised in the legs, the skin can be involved, which causes stasis dermatitis and stasis ulcers. Click below to link to more information.
