Welcome in H.C.M.
I have gone through your query regarding use of fucidine ointment for he treatment of nasal polyp.
I would like to say that Fucidine is an antibiotic having a quality to work in presence of pus as well , so it is a good antiseptic cream but it has got no role in removing the polyps.
In your case i hope you are probably not having polyp and most likely you may be having-
1- Hypertrophied inferior turbinate.
2- Vestibulitis nose.
Your fucidine ointment had helped you in vestibular infection
. It will be better to consult your ENT doctor for examination of nose and the management of lump you feel at your nose, because it is a clinical diagnosis based on physical examination.
