In order to do this you must have at least flurry or any of the other types of weapon attacks such as Critical Strike or power attack and the Force Heal power. First use Force Heal on yourself. While healing hit either Flurry or one of the other types of attacks mentioned above. Once you do this it will put the Force Heal in the queue, but instead of just doing Flurry you will also use Force Heal at the same time, but without wasting any force points. Keep doing this so you can attack and heal yourself at the same time without using up any force points.
