It defintely sounds like spread, mine is on my right lower extermity and everything you describe I have. Blankets, sheets, etc. feels like a cement block. My foot is usually colder then the other, or it feels cold and is burning up. My leg feels like it is in a vice grip esp. when weather changes more then 10 degrees. Sorry, I know that is not what you wanted to hear. I would defintely ask for an increase in meds. Maybe you can get a couple hours worth of sleep. I do my best sleeping in the recliner.
