Hi.. Thanks for the query.. As per your complain lumps under the jaw on right side of neck that also pops under the tongue can be swollen lymph nodes also known as LYMPHADENOPATHY and it is commonly due to infections in the nearby and distant regions of the body.. You should consult an Oral Pathologist and get evaluated for: 1. Any prevailing or recurring infections on facial structures like ear, throat, nose,teeth, salivary glands, teeth and gums etc or at times infections of distant body parts may cause secondary infection and swelling in distant lymph nodes.. 2..Wisdom tooth eruption or infection of the gum flap over wisdom tooth.. After thorough examination and investigations the correct diagnosis and treatment can be done .. In case of infections and inflammation antibiotics like Augmentin or amoxicillin and anti-inflammatory medicines like steroids can be taken.. In case if there is some doubt still left Biopsy of lymph nodes can be done.. Hope this helps.. Regards..
