Nerve roots after decompression can swell causing root congestion and some return of mild symptoms. This is not unusual. Other reasons could be seroma (fluid collection-not uncommon after surgery) and even a recurrent herniation but recurrent HNPs normally cause a return of relatively significant leg pain. This first thing I do in your type of circumstance is to give a short course of oral steroid.
