Can somebody do reiki healing on me to correct my accuracy level?

I feel certain that a Reiki treatment will provide some benefit for you. Reiki treatment consists of using the universal energy for the recipient's highest good and it part of the ethics of any practitioner not to diagnose need nor direct the energy to any specific condition. Share your results of the treatment with your practitioner and move on from there - deciding if you want more treatments or just experience the first one and see what happens over the next few months.
