There is the possibility of developing venous insufficiency of the lower extremities which is very common and depends on some factors. First of all, signs and symptoms of leg vein disease include varicose veins, leg or ankle swelling, leg heaviness and fatigue, leg pain, aching or cramping, burning or itching of the skin, restless legs, skin changes or rashes, ulcers, open wounds, or sores. Factors that contribute to the presence of venous insufficiency include age, gender, family history, heavy lifting, multiple pregnancies, obesity, and prolonged standing. The way healthy leg veins work is that they contain valves that open and close to help the blood return back to the heart. And venous reflux disease develops when the valves that keep blood flowing out of the legs and back to the heart no longer function, causing to pool in the legs and leading to signs and symptoms already mentioned. I would recommend that you go for an evaluation with a board certified vein specialist to check your leg veins if you are concerned. Now, approach is different for upper extremities because veins are closer to the heart, and they do not present the same problems as the legs many times do because of venous insufficiency. Your vein specialist can also do evaluation including ultrasound to check for patency of the upper extremity deep and superficial system to make sure there is not a complication if you are concern, but be aware that normal veins do tend to dilate after strenuous exercise and heat exposure. I recommend you discuss all pros and cons of cosmetic treatments options for vein appearance of the lower/ upper extremities as well if imaging and evaluation are normal. Thank you for your question.Best,
