Since your symptoms are intermittent, I am not as worried about a recurrent HNP or even a seroma (a collection of fluid). Your nerve had 5 months of significant compression so you can expect slow healing. You might ask for another course of oral steroids. Gently stretch the nerve (when it is not angry). You have to be careful as the nerve might not like overstretch initially and might not complain to you for 24-48 hours after the stretch.
