I fell down about.. seven stairs in my home. I landed on my back, I hurt my spine, chest and tailbone. Though I am unsure if I hit my head, the tailbone pain has gone, the chest pain still lingers and I have a persistent headache now. I am not sure if it is anything serious. I ve had the headache for about a day and a half now, the chest pain is only there if I try to bend over and get something.
