question: Hi I fell over a week ago tomorrow backwards and hit the back of my head on concrete. I have a cut minor that s scabbing up stopped bleeding that night and a big bump and feels really bruised all around the back of my head. My head keeps making a crunch like noise and I have to take painkillers as its so sore as healing. I notice tonight under my eyes look black (I don t normally get bags). Do you think it s just the healing process?
