Hi...yesterday I was sitting at a baby shower for hours on a small chair, when I got up my back side was sore from sitting so long....walked around the soreness went away. Got up this morning no problems....I was standing over my bed and bend down to tuck the dust ruffle sheet between the mattress and pain started on around my tailbone area...of course I ignored it and bent down again and the pain dropped me and brought tears to my eyes.....what have I done and how do I fix it....
