Can you continue to have severe congestion even 2 weeks after turbinate reduction?

Your turbinates are likely still swollen and may have crusts that are blocking your airway.  It will take time, but contact your surgeon if you still have questions since they know exactly what technique was performed.

Thank you for your question. Many patients experience congestion after the procedure. Please discuss techniques with your surgeon to reduce congestion - nasal spray and your antibiotic routine should ease the congestion. It is important that you and your board certified facial plastic surgeon are on the same page during your recovery.
Best wishes,

Congestion post nasal surgery is quite common, including turbinate reduction.  Decreasing initial turbinate swelling is often best done using either a nasal steroid or nasal antihistamine, but check with your surgeon to determine what is best for your case.  Avoid the use of Afrin as it may create rebound nasal congestion, termed rhinitis medicamentosa.  Best Dr. Anil Shah
