Thank you all for replying! It's good to see the problem from different points of view. Yes, I agree that we are all here to learn, and that we Reiki folk should not really diagnose. I think with a more receptive client I might have said something about my misgivings. I also think having this experience under my belt I will give more credence to my own sense of what's going on, but without diagnosing of course :)
Cheers,
