In my case it took 3 years for the burning sensation in the legs to finally subside after the surgery. And it wasn't just a burning - I had a lot weird sensations. I still get it from time to time in case I do a bit too much physical activity, but it lasts only few days. I was also woried about adhesive arachnoidits and had few MRIs which didn't show much, EMG was also always normal - before and after the surgery. 1 month in your case is really nothing - it's probably not what you want to hear, but with back issues you need a lot of patience...
