Thanks for posting your query at DoctorSpring.com.I can understand your concern.
You seem to be having folliculitis on the nose which is turning into a furuncle.
It's a bacterial infection if the skin caused by staphylococcus.
I would recommend that you immediately start taking an oral antibiotic like azithromycin. You will need a prescription for it. Application of mupirocin cream will be helpful. In case of pain, painkillers like paracetamol will help in controlling pain and will reduce the inflammation.
This condition needs urgent treatment. It will resolve with proper treatment.
Please let me know if you have any queries.Take care
