Hello, Welcome to Chat Doctor forum. Lump arose at the back left side of jaw may be due to-deep caries, periodontitis, pericoronitis due to impacted wisdom tooth. I would suggest you to get a thorough clinical evaluation by a dentist. Pus within the lump has to be Chat Doctor.  Associated tooth has to be root canal treated if necessary. Take amoxicillin -500 mg tablets thrice daily for 3 days along with analgesics. If there is impacted tooth, it has to be extracted or retained depending on the position of erupting tooth. Meanwhile, maintain oral care. Hope this helps.
