I have a bunion that I suspected had arthritic fluid in it and was very painful. The pain would get worse days before it rained. There were days and weeks that I had to walk with a cane because the pain was so intense. My foot would swell up. I soaked my foot in Epsom salts and pink Himalayan salts but that didn't give me much relief. I even tried soaking my feet in oregano oil, that didn't help.
Finally I thought I would try my first ever castor oil pack on my bunion for an hour. It felt like the fluid was decreasing so I used a castor oil pack on my foot for the next four nights in a row for an hour. By the second night most of the pain was gone. I can't predict when the rain is coming now because I no longer feel pain in my foot days before it rains. It feels like 99 percent of the fluid is out of my foot now. I think I will try the castor oil pack on my TMJ and over my sinus areas next to see what happens.
