I fell on the ice and hit the back of my head and back. I went to a neighbor s for an hour and just rested on the couch-talking, etc. I know I will probably be more sore tomorrow but wondered what the precautions were for tonight. I don t have a headache but at times my head feels strange, heavier, sometimes it seems like I can feel sensation in the back of my eyes. Should I stay awake for a few hours at least? The back of my head is a little sore. it is 6:18pm here. I am 68 years old, female, obese with no medications.
