Brief Answer:
Other antibiotics exist that can help

Detailed Answer:
Hello,

Thanks for posting your query,

If indeed you are suffering from nasal vestibulitis, then they exist appropriate treatments for this condition. It is often caused by bacteria but could also be due to other atypical microbes which can be determined through laboratory work by taking some samples from the nostrils.
Treatment of nasal vestibulitis will consist mainly of antibiotics (which is often taken orally) in combination with an antiinflammatory drug. Antibiotics (non-penicillin) that can help you in this situation include cephalosporins e.g cefixime. You could also use corticosteroids or non-steroidal antiinflammatory such as prednisolone or ibuprofen/diclofenac which will greatly help in reducing the inflammation hence pain.
Cauterization should not be a primary option to be considered.
I also recommend you get a health care provider or a doctor to get you examined and provide you with an appropriate treatment as I understand that you maybe seeing this as a small condition to handle at home but it is always best to allow the experts do their job. In other words, home treatment might not be all that the best option.

Hope this helps and wish you the best.
Dr. Nsah
