Bruised because..?

I drink heavily. I am a 34 F with an insatiable coping mechanism that is alcohol. Whatever that neither here nor there. I had a bruise on my L Cheekbone about a month ago. I chalked up to one so those drunken Injuries. It was sore. Fast forward. Injury is long gone, and I somehow now have the same bruise. When I press it it is sore. I did NOT fal or something. Why is this hurting? Does anyone have any insight? Or anything really… thank you
