I'm almost three weeks post-septoplasty and turbinate reduction with debriding and breathing is spontaneously worse?

The first 18 days post-surgery were fantastic and exhilarating. Sleeping better...more airflow...amazing. Spontaneously, last night, my right side became very congested at bedtime. Two nasal flushes did nothing to alleviate it, and I finally took a dose of afrin around 530am...it worked and I slept for a few hours. The day was again wonderful and clear breathing, but as soon as I lay in bed tonight..bam.. congested again. It feels 85% obstructed. Did this fail already?!
