Hi, Welcome to Health care magic forum.
As you describe, you had
ear pain,
sore throat, lump in front of the ear,and also had a
lymph node at the lower groin, of the size of a ping pong ball.
These things may not be concerned with the swollen eye lids.
It appears to be due to the
allergy, when ever you come across the allergen, you may get it.
When ever you have it note the things you have used in the previous day, and find the thing in common in such lists. if you avoid such thing you can avoid getting it.
I advise you to consult a ophthalmic surgeon for diagnosis.
I usually prescribe to my patient with such symptoms levocitrizine, montelekast, cifixime.
Wishing for a quick and complete recovery. Thank you.
