I am happy to hear you found a conservative treatment that works for you! You should not go for surgery until you simply have lost all hope. The research I have seen, which uses the Oswestry disability index, shows that the surgery will most likely significantly lower your disability index. However, it does not most probably set it to zero (it can if you are lucky). This means that there may still be some issues remaining. But if your condition gets worse and you end up lying in bed, eating painkillers all day, with no hope left, then ADR will be your saving angel.
