After giving Reiki treatments I experience chills. Not normal chills from being cold, its cold from the inside out! It takes me a couple of hours to shake it off. What does this mean? I always ground myself and run my hands under water after giving treatments to get the energies off of me.

You may want to surround & protect yourself with the white light of Reiki before you begin a treatment. Also, don't forget to prepare the room by placing a power symbol on all four walls, floor and ceiling and one large power symbol on yourself before you begin. Also, look at what's happening during the Reiki session. I know that if I'm working a certain 'being of light' during a session I tend to get chills momentarily. Try meditating on your experience and ask for guidance, then follow you intuition. Remember, Reiki should benefit both you and the client, therfore you shouldn't have any unpleasant feelings during or after a session. In Light.
