It must be for new photoreaders. I am new and I get a sensation, not quite like the ones posted though. I have a bit of a numbing sensation on the whole right side of my body. That sensetion only gives me conifidence that the system is working for me and so I just keep relaxed and reading. I never really thought about it because I was always in ALS when I experianced it and I figured it was just part of the wonders of PHR.
