So I sleep fairly well most of the night (only wake up a few times) and when I step out of bed in the morning my feet tingle. I also have a slight lower back pain as well, and it's only right when I wake up. Once I move around for a bit the pain is gone Does this mean my bed sucks? I'm only sleeping on a twin bed () but I can't afford anything else and a bigger bed just won't fit in here right now. If it is my mattress, would a quality mattress pad fix my problems? If so, what's a good pad I should look for?
