Exercise and movement, as painful as it is, definitely helps. The pain gets worse from sitting or lying down and typically improves with movement during the day. It's hard even for those close to you to understand the pain and frustration you're going through because the symptoms are not so obvious to an observer. I have read that it's sometimes referred to as the invisible disease. I hope you find some relief soon, as I know from experience that the symptoms are almost unbearable.
