Hello camyam,
Just thought you might benefit from this previous thread. Hope you enjoy the pool!

Also, I highly recommend that you read this book:
Yoga for Pain Relief: Simple Practices to Calm Your Mind and Heal Your Pain
By Kelly McGonigal, PhD.
http://yogaforpainrelief.com/.
It helped me gain a better perspective of my headaches and general feelings of crappiness

It also teaches relaxation techniques. There are parts where the vocabulary can be yoga/ new-agey but there are great parts that were worth it. Best wishes!
