Brief Answer:
bacterial infection likely present, should respond to treatment

Detailed Answer:
HI, thanks for using healthcare magic

The fact that they are recurring implies that there is likely a bacterial infection present.

She should avoid the continued use of the cortizone, this a steroid and while it would be useful initially to reduce the inflammation in the area, continued use would reduce the body's immune response and may delay healing.

She can consider trying to clean the area twice daily with a mild antiseptic if possible, may need to use q tips if it is in the nostrils and difficult to reach otherwise.
In addition, a topical antibiotic should be applied twice daily eg bactroban, fucidin, neosporin.

If there is no improvement after 1 week or there is any worsening, this may mean that oral antibiotics maybe needed for treatment.
This would require a prescription from her doctor.

I hope this helps, feel free to ask any other questions
