Suggest Treatment For Lower Back Pain And Contusion In Coccyx After Injury

I had a serious fall while walking with mail in arms (post office) a dog running high speed knocked me onto my buttocks. I hit the concrete hard enough to almost pass out. I injured lower back and had a contusion to my coccyx. I went to work after a month had to sit on the pillow for 2 years, I had swelling for about two and a half years When I carry anything heavy I feel a heaviness, and work is really rough I get the wet sensation. I recently was diagnosed with a prolapse of my uterus There talking about ligaments of the tailbone being week. Could this have been attributed to my fall and damage
