Hi,
The commonest causes of recurrent swelling of
submandibular gland if these are due to lymph node enlargement are as follows:
Infection in the
drainage areas as in your case the pharyngeal and tonsillar infection as well as tip of nose infection usually due to collumellitis.
Allergic due to eosinophilic reaction.
Primary causes can be bacterial and tubercular and in some cases of viral infection.
Hence I would advise you the following:
Go for
CT scan or MRI of the neck and pharynx to know the cause and effects.
FNAC of the largest lymph nodes.
Tests of blood for CBC, culture and sensitivity, to rule out
diabetes and other tests for
thyroid, liver and kidney functions to see any adverse effects on these systems.
Continue the medications and may need change as required.
Continue anti-inflammatory medications.
Antihistamine if allergic cause is thought about.
Symptomatic and symptomatic management.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant,
ENT & General Surgeon
