Hi, sometimes my legs feel weak but also agitated, like, they re almost numb/tingly, but at the same time, I usually have an intense desire to flex them/ move them/ stretch them, which, if I continue to do it, makes them feel better - it s as if my legs are constantly buzzing! I am inclined and I hope to believe it is just Restless Leg Syndrome , however, my grandma has MS and I m worried it could be that. It usually gets worse at night, and caffeine also makes it worse.
