Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain small recurring bumps in nostrils and directly below the nose can be due to infection that can be caused by bacteria or viruses..
In case if it is caused by bacteria it is commonly Impetigo and is caused by
Staphylococcus bacteria..
In case if it is due to virus, it is due to
Herpes Simplex Virus 1 causing cold sores..
I would suggest you to consult an Otolaryngologist and get evaluated and he can advise you a nasal swab culture, nasal endoscopy and blood tests to rule out the exact cause of the problem and treat you accordingly..
In case of bacterial infection
oral antibiotics can be advised along with steroid nasal sprays..
In case of viral infection
antiviral medicines like valacyclovir, acyclovir, famicyclovir can be advised.
Do cool compresses over nostrils..
Take anti inflammatory painkiller like
Ibuprofen..
Do saline nasal irrigations..
Hope this information helps..
Thanks and regards.
