Lynn, I have the same reaction of feeling sunburn on my hands and face after taking 4 mg of Boron. It does mention a dose of borax of 1/8 tsp for fungal infections or other health issues, but that is a big dose to start with, 1/8 tsp will have about 50mg of Boron in it, I only took 4 mg today and I burned on my hands and face. I am considering reducing to 2 mg/day for a week, with added magnesium, and see if my burning reaction subsides, then increase. Have you tried taking it with aspirin as mentioned above - did it reduce the burning?
I keep trying so hard to do the borax drink. 1/8 tsp in a liter of water. Every time I try it (drink the whole bottle by days end), I get nerve pain. All of my skin burns like a sunburn. Mostly my face and upper back.
Last time, I persisted for several days but gave up. It was too painful.
Tried it again just yesterday after a 2 mos break and again, the skin burning!
Any ideas anyone? I wanted this to work so much because I have Lichen Sclerosus (genital) and just was diagnosed with Oral Lichen Planus. They are thought to be autoimmune but it has not been proven for a fact but for now, I consider them auto immune.
I also have stiff legs and left side sciatica with a numb baby toe on the left foot. I wanted this to help with muscle stiffness (joints are fine) that may be fibromyalgia.
