should i go ahead with a Diskectomy surgery?

I have been suffering from Sciatic flare-up’s for the past two years and the most recent one has definitely been the worst. I am no only able to sleep on one side and have had to stop doing my gym exercise and even walking is very painful. Looking at some of the feedback from people who have had Diskectomy surgery, it seems as though this isn’t a miracle cure but can alleviate the leg and nerve pain. I am so fed up of this pain ruining my life but the alternative of surgery is also loaded with drawbacks not the least, being laid up potentially for a good few months. I have had this dilemma with my last flare-up and ended up cancelling the op at the last minute as it suddenly improved . but i feel that i am going to be on this Sciatica roller-coaster ride for ever unless i do something about it. Has anyone else been in the same position of these erratic flare-ups and how more frequent have they become? Currently had this bout for over 6 weeks. feeling very fed up.

Any feedback would be really usefull . thank you .
