Thanks for our query
are benign extra growths of skin, that usually do not cause any symptoms.
Sometimes they are complicated by superimposed bacterial infection
in which case they may have pus and have foul smell.
It is uncommon for a skin tag to be present in the tip of nose and produce the symptoms as you mention.
I would suggest you visit a dermatologist
for an accurate assessment of this and start medications accordingly.You amy apply topical antibiotic
creams and take oral anti inflammatory medications meanwhile will you can meet your doctor.
Hope this is helpful,
