Thank you for clarifying,
The area you are describing does sound like a lymph node enlargement and not a salivary gland (the parotid--which is located in front of the ear and along the jaw line).
The lymph node chain is likely the jugular chain. When lymph nodes enlarge suddenly, this is usually in response to an inflammatory process occuring in the area they are responsible for draining. The jugular nodes drain the ear, tonsil
, tongue and the parotid gland mainly.
Even though you may not be aware of anything going on in these areas, there may be a small irritation or infection that your doctor should evaluate you for.
You have no warning signs that suggest that this lymph node is serious--no fever, weight loss or night sweats. This is good.
At this time, I would take ibuprofen (as long as you can use this) and apply a warm compress to the area. Benadryl will not help as there is no underlying allergic process going on as far as you have described.
Rarely, lymph nodes themselves can become infected--your doctor may elect to put you on antibiotics after examining you tomorrow.
Other things that can cause an enlarged lymph node include autoimmune
infections, medications, TB and cancers (usually slow, non-painful enlargements).
So, to summarize, try ibuprofen and warm compresses tonight. Your doctor will need to check you out tomorrow to further evaluate the cause of the enlargement.
