I have a great deal of pain in my gums directly behind my third molar.  There is a thick bluish swollen area that hurts so bad when I bite down or press on it with my finger.  It has also swolen the left side of my jaw, pain going all the way down to my left lymph nodes.  What could it be?
Thanks for posting your query to Chat Doctor. For proper treatment, you should visit a dentist for radiographic and oral examination of the involved third molar. Till then, you can do warm saline rinses 3-4 times a day. Take Retool DT 3 times a day for pain relief and Augmenting 375 2 times a day. Hope I helped you with your query.
