Bump in neck!!!

unknown

Okay so me and my boyfriend were messing around and he bit my neck too hard on accident because I just so happened to turn my head and it pulled it kinda! Well now, my neck in that area feels some soreness when I turn/bend it a certain way; it also has a lump in my neck now!!? Not any bruising or marks outside just really sore to rub on and is a bump!? If I just ice it will it help???
