A feeling of discomfort in your legs may be a sign of an underlying venous disorder. These symptoms include tired and achy legs. You may experience them especially when sitting or standing for prolongued hours. During summer time, those symptoms may increase due to the heat. These symptoms are typically associated with swollen feet and ankles (especially in the evening). As for edemas (swellings) that occur after several hours spent in transportation (airplane, car, train, bus), some easy tips will help you travel long distance with more comfort. Night cramps are seldom from venous origin. It is important to know that leg pains are not all of venous origin. It is therefore recommended to see your doctor in order for him/her to do a diagnosis and to propose the right treatment for you.
