On Nov 14,2014, I slipped on ice and fell backwards hitting upper part of the back of my head very hard. I didn't lose consciousness, experienced no vomiting and basically was surprised that I only had a minor headache which was of short duration. I didn't seek treatment and felt fine overall. About 4-5 days ago, I started noticing a feeling of mild headache with a sense of fuzziness and a vague sensations of interrupted memory. I am assuming that this could be post-concussion syndrome....? Please comment. Thank you.
