Welcome to HCM,
it seems that you have got some problem in skin of nose may be you have dermatitis

take antihistamine and if require short course of antibiotic medicines.
Apply triple action cream.
If liquid is coming from the nose may be due to allergic rhinitis
,then take decongestsnt tab.
Ok and bye.
