I feel off a ladder about 5 feet. Landed on a wood deck on my shoulder that rubbed off smal area of skin on shoulder blade stopping right up to spine. because deck was 1/2 uneven, it left a narrow 1 inch wide red area that shows impact area, so it seems it might have bumbed up against side of spine but across most of shoulder blade. I lightly bumbed my head in back too. after 3 hours feeling stiff and sore but not really painful on movement. Ice on it, will take ibuprofen now. am I likely to have broken anything, or damaged back? xrays needed or scans?, or if not worse in morning should I not see a doctor.? I am 65
