Night-time nasal congestion after juice may be due to allergies or acidity triggering nasal swelling. Avoid cold or sweet drinks in the evening, keep the head elevated while sleeping, and maintain a dust-free room. You should consult your doctor to identify triggers and get proper allergy treatment.

Continue using saline nasal washes and Furamist as prescribed because recurrent nasal blockage following sinus treatment is common and may be caused by persistent inflammation or allergies. See your ENT physician again if your breathing problems continue or get worse since you could require extended nasal therapy, allergy medication, or additional testing.

A complete blockage of your right nasal sinus with occasional blood in your phlegm may require evaluation by an ENT specialist. Surgery might be needed if medicines or other treatments don't relieve the blockage or if there is a risk of infection or other complications.
