OMG, i have the same thing going on right now and it feels like it is deep in my pelvis area. It is on/off throughout the day. I have restarted my Miracle-Mineral-Supplement till my next dose of HW arrives it must be related. This a different feeling than the vibration that i get from the parasites that i feel in my legs and feet. It is more like a hum!
I thought it might be parasites but i would much rather like it to be toxins/nerve related!
