I bumped just to the left side / close toward the front of my head a few hours ago. No cut skin, no bleeding, no discoloration on the skin. Just some tenderness and and slight noticeable swelling, a subtle small bump. I also feel, rather oddly, a little sensitivity behind the Opposite side, the right, eye. I m asking why do I feel this on the opposite eye and should I worry? I have put ice on for short while and will do some again soon. thanks so much for your feedback.
