Have been struggling with shoulder pain for a year. Sometimes one, sometimes the other and sometimes both. It would often wake me up and greatly reduced range of motion. This seems hard to believe, but it must be the borax because I haven't done anything else differently, but after only 3 or 4 days, there is no more pain in either shoulder! They feel completely normal. I've been taking between 1/8 and 1/4 teaspoon in a liter of water and I drink roughly a cup of it 4 times throughout the day. I will do this daily for 10 days, then I'm going down to 5 days a week. I still have stiffness in my hands and feet upon waking up which hasn't changed much, but it's nothing compared to the pain I had from my shoulders. I'm going to continue taking it for a few months to see how much better I can get my hands and feet to feel.
