question: I am 26 years old, 5 foot 11, 205 pounds and have diabetes type 1. No allergies no other medical history. About a week ago today I was involved in a drunken fight with my room mate and he called me on in the back deck. Not thinking he was going to do anything but just threaten me I step out and next thing I know he swings a punch at him and hits me square in the chin. I get knocked out, police were called etc. Anyway I have a huge bruise on my chin and it's slowly going away but I noticed when I touch my chin there is a lump on the left side of my chin where I got hit. it doesn't hurt when I touch it, just feels like a lump. is that bad? Will it go away in time or do I need to see a doctor?
