Welcome Mo... I do yoga and find it very healing, however it has taken me years to find the right type of yoga - I do Scaravelli which is deep, slow and relaxing. Restorative yoga is also good. I believe rebounding is very good for stimulating lymph drainage, and of course massage and craniosacral therapy. On the subject of fluid - after reading Bob Dawson's excellent post and blog about Continuum Movement, I participated in a workshop which was excellent. Read about it here -
http://www.continuummovement.com/ and I recommend the book, Living on Land.
Namaste
