What Causes Bruising Betwen The Eye And The Cheek?

I have unexplained bruising on my next to my eye down my cheek on my left side of face, people have been telling me this for three weeks or so, but I can not see this bruising I also feel a slight tingling in that area. I associated that with surgury I had behind my ear to remove a lymph node when I was 18. I am under physicians care for migraine headaches they are using topamax 100mg for it. I also take lexapro 10 mg for depression,
