question: I fell about 3-4 hours ago, while hiking. When I fell, I tumbled head over heels (literally) & landed on my back. My backpack slightly cushioned my fall. I hit my head, but did not lose consciousness, haven t had any neurological symptoms. My lower back, (more towards the left side, around where the kidneys are), is hurting & burning like heck! No bruising yet, but cannot touch it. Do you think it will heal on its own or should I go to the ED?
