After I sit down for about 5 minutes and then get back up the back of my knee hurts so bad there's just a sharp pain there, and when i go up the stairs at my grandmas house the pain comes back again. I've had it for about a week and it just wouldn't go away.
Does anyone know what this is, why, and how to get rid of it?
