“How are boils inside the nose treated?”

These are usually caused by infection in the follicles of the nasal hairs. If you trim them, do it carefully as rough handling can cause the infections. Try covering the infected area with Polysporin ointment 2-3 times per day. If that doesn’t work see your ENT or dermatologist for more specific treatment.  

Nasal boils are usually simple skin infections of the subdermal region and are painful, but may be managed with over-the-counter topical antibiotic creams.

I would recommend seeing an ENT doctor. This problem can become a major emergency.

The boils inside your nose to which you are referring likely represents a condition called folliculitis which is a localized bacterial infection of the hairs inside the nostril (nasal vestibule). To avoid them, do not pick or tweeze these hairs and avoid putting your fingers, or other objects, in your nose which may lead to contamination.

Apply warm compresses to the region initially followed by an antibiotic ointment. If the problem is not improving despite this, and certainly if the problem is worsening (increased swelling, redness, pain, or any drainage), make an appointment with an otolaryngologist as antibiotics or drainage may be warranted.

The best would be to see an ENT doctor. I would apply warm compresses to the boil and then attempt to evacuate it. One can also try applying an antibiotic ointment like polysporin after applying heat. If you notice redness in the skin of the nose, it is really important to see a doctor: boils in that region can lead to serious skin infections.
In the future, to prevent them, avoid using a nose hair shaver or picking the nose hairs off: it is better to trim them delicately with a scissor...

Can apply hot, moist compresses. Best toes ENT for evaluation, possible I&D, and antibiotics. Wash hands frequently. No nose picking.
