What Causes Prominent Veins On Upper Arm?
several possible causes,usually not indicating disease
Detailed Answer:
Hi and welcome.
Veins become prominent when they dilate and it can be due to warm environment which is most common cause. But some conditions may lead to this as well,such as blood pressure variations both hypertension and hypotension. Also,if this is seen only in one arm then there could be thrombosis of superficial arm veins and this is seen after trauma,long sitting, or long pressure on hand. At this point,you should keep your hand elevated,do wrist exercises as you are squeezing small ball, put some cold compresses on arm and take aspirin 100. In case of worsening,you should do Doppler ultrasound and check blood pictures. Wish you good health. Regards
