It's one of my symptoms, my body has a constant warm sensation so I figure that could be due to the odor emanating out, or my skin struggling to release toxins which could increase the temperature to increase sweating so the toxins can be released, or maybe clusters of bacteria living on it could increase the temperature and cause the tingling sensation. The thing about this 'condition' is there's no certainty. We can only ask questions that might give us clues, anyway It's interesting because I have GERD too, stomach burning, white tongue, but we're all so different. I may suggest that you do a lot of internal cleansing because whatever is causing your problem is obviously internal as the toxins from some malfunctioning organ are being excreted on your body attracting bacteria.
Congratulations on finding your cure and I hope you live life to your fullest :)
