As the title says. I go for a 20 minute walk and when I stop moving, I'm not feeling tired or even agitated at all, yet my legs feel like they're pulsating in different areas, always near the skin. It's not synchronised with my heartbeat. It stops after a few minutes.

Chat GPT says these are just muscle twitches caused by dehydration or lack of electrolytes. I'm not convinced. Why does it feel almost on the skin and not deeper in the muscles? Why do I feel it after a 20 minute walk that doesn't make me sweat but I don't feel it after a 40 minute leg focused workout???? Wouldn't that be more strenuous on the legs?? Does this thing even have a name?

Thanks
