Hello
Thanks for posting your query at DoctorSpring.com.
I can understand your concern.
The picture is actually quite blurred. I would like to request for another picture. You can also take one zoomed out picture.
From what I can see, it seems to be infected. Neosporin cream is available over the counter which is an antibiotic cream however, it would be best to use mupirocin cream twice daily, neosporin cream at times could cause irritation. Mupirocin cream will require a prescription from your doctor.
You can leave the area open.
Hope this helps, would be glad to answer any follow-ups.
Take care
