Hi , In october I was diagnosed by ENT that I am having ACUTE TONSILITIS .ENT prescribed me antibiotics , muscle relaxing tab and  zincovit tabs than she also suggest me to visit a dentist to remove my molar teeth as per her words she suspect my wisdom teeth is impacted . I went to dentist , he ordered OPG XRAY and yes I had a very badly placed 3rd molar so he asked me to remove it . I said yes But during this procees I also had a NECK USG test where NO ABNORMILITY DETECTED remarked in report . After my teeth extracted ( surgical ) i have noticed slight swellon thing like very small moving while touch things in my submental area . OPG XRAY says nothing else except the wisdom tooth and USG NECK also said No issue in thyroid , isthmus ok , partoid OK , OESOPGAHUS NORMAL , submandibular glands NORMAL , No enlarged lymph . But what this is at my submental area . It caused pain for just 3,4 days during tonsil infection , than it returned little smaller after tge infection gone ( as ENT)
