Hello,
Thank you for your query at DoctorSpring.com
I have seen the images, and I would strongly disagree with your pharmacist.
Since you're a chef and you stand for such long periods, you need to get the wound cleaned with betadine twice daily and apply a dressing on it.
If there is any discharge or pus, you may also need Mupirocin ointment.
Hope this was helpful,
Feel free to discuss further.
