Talk to Vascular Surgeon on The Veins Motion

Asaalam O Alaikum Dr. Sahib, it has been almost a month that I sometimes. especially at night. So my veins are moving intermittently. I mean, like a pump, I feel it. Sometimes it's in the lower part of the foot, sometimes it's in the hands. I feel like there is something in it and what is circulating this Sir, what could be the reason and if there is any treatment, please provide information. Thank you.
