Thank you for your question.
Does he have any other medical problems?
Is he on any medications for anything at the moment?
Please let me know.
I would like to add that since the bump is increasing in size, I would recommend that he be seen as he will also likely require a course of an antibiotic to make sure that the bump is cured effectively.
So that is what I would recommend doing.
Meanwhile he can apply some topical antibiotics like neosporin or polysporin.
Let me know if you have more questions.
