I hate to say it, but as someone who has had multiple concussions(Horseback riding) I remember I dealt with very painful headaches for up to a year including spinal fluid dripping from my nose. So it can take a few days, weeks, months or even a year. I had a tender head as well. And felt foggy. The headaches were nauseating and awful, and had one at least once a day.
