[|Human|] Hi, I just notice that my left bottom gum is swollen. I used my hand to feel it and itd really hard. I had an operation slightly above the gum area where my 2 back teethe were removed due to cyst infection 15 years ago. Right now,  I am still recovering from flu and cough. Can this be a side symptom of my flu? Im just worried if my cyst reoccur again. Should I be worried?
[|AI|]  It may be a recurrence of cystic infection but since you have been asymptomatic for 15 years after its treatment chances are lesser for that, you may rather suspect an infection due to some other adjacent tooth, it is not due to cold and flue.  To be sure I would suggest you to get it examined at the earliest and also get a radiograph of that region to be sure of what it is rather that delaying it and causing it to increase further.
