I had 6 complimentary visits to a pal who was setting up in a posh spa.
Don't know how typical this is, but I lay down, fully clothed but shoes off and the healer moved his hands over "chakras" - like acupuncture nodes, without any contact.
I had some aches & pains, and he spotted the areas, and actually laid hands there, without me saying where. Quite impressive.
After an hour, I got up & felt a lot better, but I'd had a good rest...
Can't say whether it worked, whether the pains went away of their own accord, but it did no harm.
