My inclination is to say that any symptom following a single drop of activated Miracle-Mineral-Supplement in a glass of water isn't very likely. Though, I'd be interested in hearing if the condition persisted over the course of intermittent trials. (5 days off type of thing).

As for jaw pain, there's always the possibility of interactions between Miracle-Mineral-Supplement and underlying conditions as well as the potential for irritation as the acid component could irritate an existing lesion in a tooth etc. - tough to say without additional information however; amounts, solution type, application etc.

Remember that Miracle-Mineral-Supplement is essentially bleach (sodium chlorite and citric acid /or HCL combine to form chlorine dioxide). In higher concentrations it can be very irritating to mucous membranes.

DMSO is also extremely effective as a skin penetrant (even more so when it comes into contact with mucous membranes) so anything dissolved in it (the Miracle-Mineral-Supplement and anything else in the rinse) will be absorbed very quickly. If the dose was too high for you (everybody reacts differently), then the extremely quick absorption may very well have irritated the area it was most absorbed into.

Another possibility is that you may have come into contact with some toxin or contaminant completely unrelated to the protocol. DMSO can cause contaminants, toxins, and medicines to be absorbed through the skin very quickly, which may cause unexpected effects. Just make sure you're careful when handling DMSO.
