Hi folks. Original concussion resulted from an impact to the back of my head. At work tonight I got inadvertently knocked in the temple by a coworkers elbow. When I got home it seemed that the headaches in the back of my head, where the intitial injury was located, got much worse. Is it possible that there was some sort of diffuse damage, so that even though the elbow struck me on the temple the metabolic reaction effected my entire head or something? Very frustrated that my symptoms have returned after two extremely minor impacts in the last two days, and concerned that even though these hits were minor, they were enough to inflict some damage on a tender, post-concussion brain.
