After briefly becoming groggy and laying down for bed, I started feeling the electrical buzzing in my head that I believe to be coming from something external stimulating something inside my body. They have modified their tools to again allow a sharp pain in my chest, but it is still not the same as it was. If I hold my fingers on my shoulder hard, it does stop them from being able to stimulate whatever is inside me near my chest. This has been going on for 5 hours now.
