Hi Doctor, I fell the other night and I hit the left side of my head like where my temple is located. There are lumps there. I went to the ER. They did a CT scan and was told it likes normal. Well, I m still really tired, short-term memory loss, vision is a little more off than normal, and nauseous a couple of days after. Also, my back hurts more now post-epidural, spinal tap and blood patch from a few months ago. Should I be concerned?!
