Suggest Treatment For Headache And Dizziness

I need to know what to do... I am in a relationship with a man who is abusive and a few days ago he punched me over and over again in my head and my ear.....I still have knots on my head that are still sore... I have a head ache all the time and when i bend over i get dizzy... and my hearing in my right ear is foggy... should i go to the hospital and get checked out and could i have a more serious thing going on that i just dont know?
