Suggest Treatment For Headache,painful Bump On The Forehead And Vomiting

Hello, I fell and hit my forehead 2weeks ago. It was a bad bump and I was vomiting afterwards so my husband took me to the hospital where they did a CT scan and there was no damage to bones etc. I was kept in for observation for 6 hours and then allowed to go home. I subsequently developed a black eye and bruising down the side of my face which is gradually getting better, however my husband has been hassling me that maybe the doctors didn t do a good job. I was a nurse before I married and have told him that I do not have any headaches inside my head, rather just minor pain around the lump on my head that I feel is related to the trauma and it is easily treated with paracetamol. He is suggesting I need to go to see my own doctor, but I am fine with resting and waiting for the lump and bruising to resolve itself. The doctor at the hospital told me that it would take up to 6 weeks for the injury to heal and I can see improvements every day, but my husband cannot understand why the whole side of my face developed bruising after a few days. Can you explain that to me. Thanks Trish Boyce
