Hello,
Thank you for your query at DoctorSpring.com
I understand your concern and have reviewed the picture you shared.
I can appreciate the swelling, and it does look infected.
In such cases, it is better to get it examined by a physician, and if required the pus can be manually drained, which will help in healing. A course of antibiotics and Mupirocin ointment will help in faster healing.
Feel free to discuss further,
Regards.
