Hi.
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you have got infection at the piercing site of tragus and it is leading to swelling and discharge that seems to be pus..
It can also be infection secondary to skin irritation caused by wearing earrings not made of inert materials lke gold or plastic..
Other metals can reach with air and water and decompose..
The decomposition products can cause skin irritation..
I would suggest you to remove the ear jewellery. An clean the area with antiseptic solution..
You can also clean the area with antiseptic solution and apply moderate pressure to release pus as much as possible..
You can apply Antibiotic Ointment and
steroid ointment over it..
In case if still it does not resolve consult a General Physician and he can advise you
Oral antibiotics and painkillers..
Hope this information helps..
Thanks and regards.
