I fell down the stairs about a week ago and now I have a constant headache, nausea, loss of appitite , and have a hard time falling asleep. not to mention waking up. It also hurts to bend over, becsause it feels like someone is pulling my spine apart like a traction table
HiYou have hurt your spine during the fall, with what symptoms yoi have described it can really be troublesome.Please go for a mri spine to rule  out the exact injury.Meet a neurologist or a neurosurgeon,As the signs you have elicited shows variation in the intracranial pressure, which can be dangerous if not treated.Take care
