Hi
Welcome to the MedHelp forum!
Watery nasal discharge is seen in allergic rhinitis, infective rhinitis, viral infection, rhinitis medicamentosa (inflammation of the nasal mucous membrane due to application of topical nasal sprays, ointments and drops), or due to vasomotor rhinitis (in response to dry air).
It is difficult to comment beyond this at this stage. Please consult an ENT specialist.
Take care!
Thats perfectly normal, I work in a Nursing home and most of the Elderly Men and Women have expeirienced this. It's just from Allergies, it's considered "Drippy nose" Either a sinus infection is about to come or he already has one. Ask one of the nurses to see if they can place him on allergy medicine.. most of the time a Steamy shower will open up his nasal passages. and never forget to BLOW BLOW BLOW!
