Thanks for writing to H.C.M. for your query.
I have gone through your query regarding small cystic lump in ear lobule and followed by swelling in ear lobule and painful enlarge node behind the ear.
I would like to tell you that small lump in ear at piercing site may be-
(2) Sebaceous cyst
I think you are having Keliod because your lumps are on both side were near the piercing point which is in favor of Keloid on the other hand sabeceous cyst is unlikely to be bilateral. The keliod gets infected thus your ear lobule became swollen and draining lymph
node behind the ear near the angle of jaw get enlarge and painful.
As far as treatment is concern you should take antibiotic, anti inflammatory,drugs and to contact surgeon to remove it , and simultaneously use of anti scaring cream locally to avoid recurrence of it.
