Almost everyday, usually when I'm resting (but not always) my back gets very restless and sometimes painful. It's happening as I type this. It prevents me from sleeping and disrupts my life. I can't tell if it hurts or it's a VERY uncomfortable restless feeling, but it gets so bad that I'm almost to the point of tears. I found that heating pads work well to temporarily ease the pain. But if I take it away, it worsens. Does anyone know what is wrong with me??
