Hi Dear,
Welcome to HCM.
Understanding your concern.
Thanks for your concern . The symptoms you mention in query are can occur due to two things . Firstly there are many lymph nodes in that area so the lumps can be lymph node swelling , which usually occur due to infection. Secondly the lump can be due to blockage of
submandibular gland duct , which occur due to stone or any foreign body such lump is called
mucocele.
I would suggest you to
consult ENT specialist (ear,nose,throat) for proper examination . Doctor may order X-ray or
CT scan of that region to confirn the diagnosis .
In case of lymph node swelling doctor will prescribe antibiotics at least for week along with anti inflammatory drugs .
If it is mucocele then doctor may remove it surgically or perfoem marsupilization.
Sometimes the lump that is immoveable ,hard and slow growing could be a cancer so it is important to visit doctor and get it checked.
For now give warm compresses and take advil (if not allergic to it ) or
tylenol for uncomfortableness and swelling.
Hope your concern has been resolved.
Best Wishes,
Dr. Harry Maheshwari
