My only guess, and it is just that, a guess, is that you are focusing an incredible amount of energy to one spot, using your brain. Too much force on one body part over periods of time is due to make it sore. Such as with work or exercise.
My main issues with this TK field are the energy currents and vibrations. Ever since I found out one month ago, I've been feeling fire and electricity running through my hands and feet. I also get major cold spots mixed in as well, sometimes throughout the rest of me.
The vibrations are nasty, at some points during bad days, my whole room shakes. No fun at all. :-/ A MAJOR step up from blowing out lightbulbs and short circuiting electronics.
Anyway. Enough rambling. Hope I've helped with some starting points for you. Namaste.
