[|Human|] I was walking and a friend said hi so I turned around and not know that there was a brick post in front of me I slammed into it with my forehead there is now a very large bump with a red line down it on my fore head how long will it take for this to go away and why is there a red line in it and how can I make the bump go away
[|AI|]  Hello and welcome... No need to worry about.It's a kind of normal body response to the injury called inflammation... It is characterized by pain, redness, swelling,hotness if the effected area. This bump is due to accumulation of extracellular fluid which contain useful products for maintaining the normal structure... You can say that your body immune system is fighting for down there in the bump. It will disappear in one week... For pain, you can take ibuprofen 400 mg twice a day... Hope you'd understand... See you back in good health...bye
