Hi. I woke up yesterday and noticed the skin under my left eye, below where my tear duct is, was black and blue. I do not remember either hitting myself or my glasses being pushed into my skin. Someone I work with said her friend had this and was told it was caused by her blood pressure, which was very high. I take my medication faithfully. Should I be concerned about this or do I just not remember bumping myself? If I bump myself, I seldom remember it unless it causes extreme pain.
