<s>[INST] hi I have a large lump above my gum line just about where my cheek is.  It is on my right side.  It is very tender when I touch it but I didn't even notice it until today when I was flossing.  I have also had headaches, runny nose and my ear sometimes feels clogged but nothing is there. Please help. [/INST] Thanks for your query, I have gone through your query.The large lump over the gumline is because of the abscess or collection of pus secondary to teeth or gum infection. Consult a oral physician and get it evaluated. If I am your treating doctor, I would have suggested you to take radiographs like RVG or IOPAR to rule out gum and teeth infection.If it is a gum or teeth infection i would have prescribed a course of antibiotics like amoxicillin 500mg and metronidazole 400mg tid for 5 days (if you are not allergic). Then i would have suggested to go for scaling and root planing for gum infection. RCT or extraction if it is a tooth infection.I hope my answer will help you, take care. </s>
