I bumped my head rather hard a few days ago on the back hatch of 20+ year old Jeep grand Cherokee as I was loading plants into the back in a parking lot at Lowe's. The darned hatch only goes up about halfway now, and i didn't look to see if my mother had raised it. The impact was hard enough that I was stunned for a couple seconds and I saw stars, but remained fully awake and aware. My mother told me to go sit down as she finished loading.

That was Wednesday evening. On Friday evening, I began to get a mild headache that has yet to go away. I took an Alleve last night and the headache is still there, but not as annoying. It does feel worse now that I massaged my head at the sight of the knot and am writing this post. I also noticed I am rather light headed, but that could be from not sleeping. I hadn't slept Friday night, but did get a nice long nap in all day yesterday, but hadn't slept since about 4 in the afternoon.

Should I be worried enough to go to the ER? I am not vomiting at all or feeling confused and forgetful. I mean, not more than normal anyways.
