Welcome to HCM
Understood your concern
Your right..Yes..Probably it is an abscess
if you prefer self treatment, just clean the wound regularly taking all aseptic precautions. Apply Mupirocin
oint. Usually it heals within a few days.
Visit to a doctor if,
1.You feel daily dressing should be done in a health care facility.
2.The lesion deteriorates with self treatment, indicating possible requirement of systemic antibiotics.
Usually pain killer tablets are not needed, but if it is intolerable, you may take one.
Thank you very much for consulting us.
Get well soon.
