I'm glad that's not the case. I'm sorry you have been through so much. You've certainly been proactive about trying things to help your constipation.
Unfortunately, it isn't a good idea to take Miracle-Mineral-Supplement until after you open up your eliminarive channels. People who are chronicaly constipated have accumulated so many toxins because of the wastes remaining in them for so long. If you take Miracle-Mineral-Supplement in that state, it will release a tremendous amount of toxins. Your body will be even more toxic if you can't eliminate them. Miracle-Mineral-Supplement definitely is not a treatment for constipation. Diarrhea is how some people's bodies deal with the toxins, but it won't necessarily give you normal bowel movement when you start taking it. I would guess your rash is the body being so overloaded with toxins that they are coming out through your skin. Your body may react almost like it is allergic to your own sweat or perspiration (that is because it has acidic toxins in it).
I would suggest that you alkalize your body by looking at a chart on what foods have an acidic effect and which have an alkalizing effect. Since you already take greens you may be familiar with that ptinciple. Excuse me if I'm "preaching to the choir here!" Also, you may want to drink a glass of water with a teaspoon of baking soda in it before bed. But, only if that blood pressure reading was because you were nervous. If it remain that high then the baking soda may make it go up a bit. If so, Himalyan Sea Salt , or celtic salt would be better as they don't seem to cause that rise. Of course drink lots of water, don't overeat. I would avoid any activities that cause you to perspire until the rash is under control.
Alkalizing baths would be great also. I would keep them just warm for now not hot, after the rash resolves I would make them warmer. Add Epsom Salts , baking soda or Sea Salt , Hydrogen peroxide. You may want to spritz your body with H202 after bathing and let it dry. There are many more things I could suggest, but mainly you need to get your colon working. Have you considered having colonics? If that is too much for you, you may want to go to the constipation forum and see what natural methods people are using. There is a capsule with powder called "oxycleanse: it is very gentle, it has a form of magnesium that is oxygenated and works wonders for many people. I hope some of this helps. Keep posting anf let us know how you are doing! When you start on MMS again. I would suggest staying at one drop for a month or so depending on how you are doing.Feel free to ask any questions, lots of knowledgeable people are on this forum. Good Luck!
