Oz this doesn't fix the problem but it does help with the swelling and pain. Apple cider vinegar and a brown paper bag. Tear up the brown paper bag into strips and dip into the vinegar. Wrap affected body part in the wet strips for 30 minutes. Remove and rinse so the vinegar doesn't burn your skin. DON'T EVER fall asleep with this on. I ended up with blisters! This is Great Granny Hensen's cure for sprained ankles and anything else that made joints swell. She used to swear that it needed to be brown paper that a white paper sack wouldn't work right. Who knows. Considering that DMSO (
Dimethyl sulfoxide) is extracted from paper pulp, the vinegar may be soaking out trace amounts of that as well (which would be most likely in brown paper than white paper).
DMSO does work well but you must be VERY careful in it's use because it can snatch other chemicals and drag them deep into your bones. My dad used it but he never used anything to apply it but clean white cotton. He would wait until it was totally dried and absorbed before dressing so it wouldn't snatch the dye out of his jeans and drag it inside his body. For those of you who might not have heard of this it is a common veterinary medicine used with race horses extensively. Smells like garlic and 5 to 10 minutes after you rub it on you will taste garlic in your mouth. Makes it impossible to do a double blind test with a placebo so it has never been able to be approved for human use by the FDA. And there are dumb people that would not use proper precautions and accidentally poison themselves by contaminating the DMSO.
