About 1 1/2 weeks ago I hit my head on the edge of the kitchen counter while bending upwards after picking up some trash. Didnt seem to have hit it that hard. Really didn hurt at all. Which I found odd. Hit a few inches back from my hairline. Lately my head feels full in my forehead and my tongue seems numb a bit. Not sure if numb is the right term. Should I be concerned. I've had no confusion, headaches, etc. ..
