A pain rises from leg to whole body. Up.

Actually, I feel a kind of rising sensation from the soles of my feet up to my ankles and knees, and it happens much more when I put my feet in a cold place. When I pour cold water over my body while bathing, I get the feeling that “something is about to rise,” as if it will spread throughout my whole body. On other days, this feeling is present but milder. However, on certain specific days — for example, Wednesday or Sunday — if that rising pain starts in my body even once, it troubles me the entire day. When that pain rises and spreads through my whole body, I feel very uneasy, I don’t feel like doing anything, and if it happens while I’m talking to someone, it feels extremely unpleasant. After a while, I return to normal, and then I can’t clearly remember what caused it or what exactly happened. I’m very worried about this, especially with my board exams coming up.
