I am having what they now believe is nerve related pain from a radioactive dye they injected me with to do a bone scan of my injured neck...this has been ongoing since end of October, and no treatments seem to work, so I am cutting them all off one by one, and feeling much more human. I KNOW certain stones have always felt "right" to me, and I carry them around as a worry stone. Have done all of my life. I am getting scared the dye did indeed cause permanent nerve damage. My body does not especially like chemicals of any sort..
