question: I have been experiencing a clavicular fullness, neck fullness and jaw pain for the past few years ..been tested for everything (nothing lfe threatening).. all they found was an abnormality in my submandibular gland (cystic) and a ranula. In past few months under my tongue is swollen and VERY painful (pain radiates to jaw) the swelling (mouth floor and clavicular)and pain come and go and I cannot tolerate the pain and numbness /Tingling anymore, nasty taste after swelling goes down... after reading a lot ... how do the drs distinguish if it is a ranula or a plunging ranula? Should I be worried?
