Hi! I live alone and have called in sick to work but I need to collect my ds from school at 3pm and I literally can't get out of bed as my back's spasming so badly (pretty sure it's a pulled muscle) I've been taking Naproxen and codine since Monday but no relief yet. Can anybody suggest some gentle exercises I can do to loosen it up in bed so I can at least get mobile? I've run out of water and I can't get to the toilet. Thanks!
