I have had a cold for over a week. My
possibly Boil. Oral antibiotic recommended
Hello and welcome to ask a doctor service.
I have reviewed your query and here is my advice.
Most likely it is due to a boil/ furuncle inside nose which is causing the nose to become red, swollen and painful (i.e cellulitis). The anterior part of the nasal mucosa is hairy and it can get inflamed due to infection of/about a hair follicle.
I suggest you take an oral antibiotic e.g Amoxicillin and Clavulanic acid 625mg, three times a day for a week (you may need a prescription from your local physician for this).
In addition, I suggest you take an oral anti-inflammatory/ painkiller e.g Acetaminophen(Tylenol), two to three times a day.
Hope I have answered your query.
Let me know if you need any more assistance.
