Brief Answer:
three likely causes

Detailed Answer:
Hello and Welcome

I appreciate your concern

Based on your description, the likely causes are

Herpes zoster
Trigeminal neuralgia
Upper respiratory tract infection

All three can present the way you have described the case. If there is an associated vesicular rash slowly appearing on the affected side then herpes zoster is likely.

If the pain is sharp and debilitating then trigeminal neuralgia can be looked for clinically and history of local ENT procedures should also be taken.

Oral and ENT examination should be done to look for a possible infectious cause in the affinity.


Wishing you best of health

Thanks

Brief Answer:
Lymphadenopathy

Detailed Answer:
Hello again

Localized lymphadenopathy does occur and is possible. A single node is unlikely to do so. However, a group of lymph nodes can produce the same effect.

Thanks
