Reiki would be a great idea, although I would be personally be much happier if you were taking a class one to one, so that the master teaching you could ensure you were totally comfortable all the while. Learning level one is all about self healing and using energy to help the body to heal itself, and that would be the level that I would suggest you spend time at, so that all your enegy would be spent getting you better before going onto further levels that would encompass sending reiki to others

One thing to remember about reiki or any other energy therapy is that 'healing' does not always mean 'cured'. The two things are different.
Have you tried the energy ball exercise? How did you get on?
