No, Reiki practitioners are not medically trained to provide diagnoses. While a practitioner may sense tension or tingling in certain areas of your body during a session, this should not be mistaken for a medical diagnosis. It simply indicates potential energetic blockages or issues in those specific areas. Any observations or discussions with the practitioner should not replace professional medical advice or treatment. It’s always advisable to consult with a qualified healthcare professional for any medical concerns or diagnoses.
