I've been having weird feelings around both knees for the past couple weeks, i went to my doctor and he said i sprained my knee, but its not even the knee, it's the skin around them. I get a weird pain type thing on my SKIN. it burns and is sore when something makes contact with it, no rash, no bumps. when i touch the skin with cold fingers it hurts ... I've never had this. does anyone know what it could be? it's the skin all around the knee, it comes and goes and stings.
