When you're diagnosed with a concussion, the treatment center is required to provide after care instructions on what you are and are not supposed to do. It clearly states symptoms can last up to six weeks, and that you should avoid vigorous activities and sports. Golf is a sport.
There's a reason you're supposed to rest and be careful after a concussion. YDI for not following the directions explicitly given to you at the hospital about concussion after-care.
