Well for once i get to go over to the nuttier side of the fence. : )
I have some areas of my body ( joints and lower right leg specifically) where I always feel resistance to the energy. Usually when I start I just feel the resistance in those areas, but as I go on i feel more of a physical discomfort/pain. It usually gets worse as I continue the treatment but by the time I am finished or almost as quickly as I stop the pain alleviates. Only to start up again next treatment.
I believe this is one of those times where Reiki is causing what we deem an unpleasent experience, even though it is doing right. I feel that the area being damaged and needing Reiki is well obviously resistant to the flow of the energy.so one may experience discomfort. Kind of like how you can recieve Reiki for a cold and have the illness seem to increase but then get over it at an increased rate.
I would say to keep going unless it is unbearable.
