You conditions sounds terrible and I am sorry to hear you are having to go through such a terrible ordeal.
Unfortunately, I can't think of a single ailment that could relates to the symptoms you've listed. And as I'm sure you know, for a regular Joe's like myself to try and diagnose you would be pretty far fetched to say the least(I'm not doctor!).
However, I wanted to comment on your comment about doctors. For one... try to keep in mind that doctors are just people too. And that all they can do, is to try and identify your condition based on recognizable symptoms. I'm not making excuses for them of course, I'm simply saying, that it's likely that they want to help you but don't have a clue as to what's wrong. However... I do find the 2 week waiting period to be rather excessive!
Anyways, here's my take on the Miracle-Mineral-Supplement reaction. I've been taking Miracle-Mineral-Supplement to treat a rather severe systematic infection. And if/when I was experimenting with different intakes, I noticed that when the infection spread throughout my body that the Miracle-Mineral-Supplement would often cause a burning sensation when it would attack or fight it. I'm not saying your reaction was the same, but... if you were feeling a burning sensation after taking MMS, do you feel that could be due to the MMS reacting to whatever was making you sick?
In any case, as a layman, when I read your initial symptoms, I'm tempted to say the aching and burning almost sounds neurological or nerve related. Again... I'm not trying to play doctor or anything(I don't know much), but that's what ran through my mind when I read your story.
Aside from that, I can't think of anything else to say that might be of value to you. Other than I truly hope you find relief soon and that things work out for you.
