The National Center for Biotechnology Information claims that a regular pulse can occasionally cause the skin on the arms and legs to rise and fall. Rather than in veins, arteries experience the visible pulsation.
Dr. Bennett Werner, a cardiologist, notes that the radial artery on the inside of the wrist frequently exhibits pulsating. This can occasionally happen when a blood vessel bulges. When the arm is raised above the heart’s level, the bulge usually goes away.
It is most likely normal if there is no pain linked with the presence of visible pulsation. According to Dr. Mitchell Vogel, a doctor should be contacted if the apparent pulse is accompanied by an unusually rapid heartbeat, discomfort, or other cardiac symptoms.
