Thanks for writing your query.
After reading your post, it seems that you have got infection on the ear lobule.
You should consult a doctor and get the pus drained under aseptic conditions.
You can take pain killer like Ibuprofen
twice a day after meals to reduce the pain and swelling.
Antibiotic can be added to control the infection. Culture/senstivity test of the pus discharge can be done to know the appropiate antibiotic for the causative organism.
I hope this is helpful to you.
