Hi Eva,
Hope you are feeling ok and staying positive. I've been thinking about you!
I've got a couple of links for you for some meditation information on controling pain. (There are so many available) I have a book at home that has Mandala's to focus on for meditation, when I am in bad pain I meditate to allow my body to free itself from the tightness and it allows me to let go of the pain. (also allows your pain meds to work better)
Treat yourself to a book about meditation, or download some relaxation music on your ipod/computer to listen too.
