Hi Llonsdale, Thanks for writing your query. After reading your post, it seems that you have got soft tissue injury over your scalp. Black eye is a common symptom after forehead injury. It takes few days to weeks for recovery from black eye. Cold compress will help in relieving the symptoms. Swelling or bump will also subside in few days time. If pain is severe, you can take pain killer like Ibuprofen one tablet twice a day after meals along with an antacid. You can continue use of medicated creams for bruise. Your injury seems to be superficial, still you should get a scan of your head done as you had an episode of unconscioussness. You should get immediate medical attention if following symptoms develop :- unconsciossness/nasal or ear bleeding/nausea or vomiting/irritability or disorientation/memory loss/seizures/difficulty in balancing the body. I hope this is helpful to you. Thanks.
