I had turbinate reduction 2 weeks ago. 3 days ago my ent removed the crusts. this helped alot but congestion has returned. is this congestion normal?

Well : It can occur the surgery treats the mechanical obstruction it does not treat the allergic component. You may be having nasal allergies. Consult physician for specific diagnosis and treatment

Recrusted?: Often it takes more than one or two debridements depending on the nature of your mucous membrane and healing, as well as your vigilance with nasal saline irrigation and/or use of nasal emollients such as Ponaris.
