The back of my head and shoulder hit the bottom cabinet hard. It hurt, no black out or dizziness. That was a week ago this past Sunday. Yesterday and today for some reason it is bothering me. Kind of tingling. I didn't put ice on it when it happen and should have. I am now. I have a slight headache nothing major. Is it normal to have it still be tender and hurt when I press on the place where I hit or does it take time for the bruise to heal. It doesn't really feel like it is swelled up.
