My Concussion occurred 8/3, immediately went to doc, got 5 stitches. I took me at least 2 months to feel somewhat like myself. In Jani went to the ER because I had lost the ability to walk - truly, and I m no sissy. Oh, by the way, my mother was dying during this time. She died 4/28/16. Maybe relevant, maybe not. What concerns me is that my imbalance loss of memory, insomnia, have returned. Should I be concerned?
