this is the million dollar question. the best indication for spinal surgery
are symptoms due to neural compression and from the sound of it you do not have this problem currently. some of the ongoing symptoms that you have following your surgery do sound neurological in nature and so some neuromodulating drugs may be of benefit to you such as pregabalin
in addition to your analgesics. it is very early following your surgery and so I would not be in any rush to proceed with further spinal surgery until you are sure that you have fully rehabilitated by non-operative means. if your pain is substantial and it persists long term then you may feel that you have nothing to loose by further surgical intervention although such and operation at not get rid of all of your symptoms.
