I have fibromyalgia, which is characterised by chronic pain caused by muscle tension. Out of all the methods I've tried to limit pain, from meditation to weight lifting, cuddling has been the most effective. All muscle tension just instantly melts away. I wonder if oxytocin would work as a light pain killer.
