I have a clear sticky discharge that sticks to the walls of my nose & builds up until the nostril is full. then it starts going down the nasal tube. i pull it out but it just keeps coming. what's it?

Allergies???: Sounds like allergies. See allergy specialist. Also could be local diseases of nasal mucosa- therefore- also can get ENT opinion.

Clear mucus: Has several possible causes from normal nasal secretions, allergic rhinitis, post nasal drip and other mucus-producing entities. Have an in person exam to get the most accurate diagnosis. Regards!
