Sorry Danni but Voltaren and the likes are OUT during pregnancy. Heat packs work wonders. Like Mooshie said, a ball between the sholders rolling around helps heaps. You can buy special ones with spikes on them and they really get into the muscles - we use them in the hospital for staff! They are great for getting circulation going too - I love rolling them under my feet. But just lean against a wall with the ball between your shoulder blades (or wherever you like) and move your body to move the ball. Takes a little to get used to but it is great.
