Hey Gertrudes, I've been following your thread and am rooting for you. Sounds like quite the nasty burn you've had. Several days ago I applied too much magnesium oil (over the course of three days) and had as a result some surprising but temporary burns on the back of my legs. It's of course nothing like you've experienced, but I didn't know magnesium could burn like that. Good to hear you're getting some temporary relief with aloe and hopefully you'll be getting some DMSO sooner than later.
Although I have some hesitations about the use of Reiki, I've found it has remarkable results in healing burns. It's probably the only thing I really use it for. It doesn't necessarily heal the wound of the burn, but in my experience it does take the burn out. I don't know if you know of any Reiki practitioners or if you are one, but it's something to consider.
Hope you're better soon.

I really hope you find some relief soon. I wonder if maybe the muscle relaxing properties of the magnesium have caused the esopageal sphincter to relax allowing stomach acid to spill up into the esophagus. Or maybe the sphincter was damaged by the burn. If the sphincter isn't closing properly, for whatever reason, this would explain the reflux-like symptoms, like it getting worse when you lie down. I don't really have any suggestions, but I certainly hope you feel better soon.

. I didn't realize that magnesium pills could do that, but the ones I take are so big I can see how they would easily get stuck.
