About a week ago I was sitting on my bed and got frustrated from studying for college and slammed my head backwards and hit my headboard (not that hard). After about a day or so, it began to feel tender and would almost cause a little bit of a headache on the side where I hit it (left) and the muscle that goes up the back of the neck on the left side would begin to ache with the headache. I have had no blurry eyes, no memory problems, just tenderness and everynow and then a little headache. I have actually found that when I get stressed out (studying, etc) that is what triggers it. My dad is a massage therapist and when he massages that neck muscle, it completely goes away. I am a very anxious person, so I am probably making it worse always thinking about it. Is this just a very tender spot of the head? Should I be worried about anything?
Thanks
