I have an unexplained brusing on my left side of my jaw next to my ear, below the hairline. Last week I woke up one morning feeling a little sore, I thought my left lymnode was swollen. It felt & looked the same like my right side, but felt sore when i touched. Three days later i noticed the bruise started to appear next to the side of my left ear. The bruise has gotten lighter after 4-5 days, so is the pain. I had my dentist checked it out & he didn't find anything wrong. He said probably my one of my saliva glands was clogged. Should I see a doctor about my condition? Thank you,
