about 3 days ago i fell off my houses fence that was like 13 feet high and i landed in a V shape on my tailbone area. at the moment i experienced a huge amount of pain but i managed to get up and try to walk it out. i still have a lot of pain throughout my whole back even up to my shoulders. it hurts to sit, i can barely use the bathroom because it hurts. i just don't know if it's temporary, a bruise, or a fracture. is it worth me going to the doctor
