You have pain because of annular tear in in the cartilage
and disc bulge compressing nerve
. However, pain by itself may not be indication for surgery . I suggest you for the following:
(a) Have a review by neurologist
weather there is any neurological deficit or not
(b) Your doctor may consider pain relieving medicines, rest and physiotherapy
(e.g. short wave diathermy etc)
(c) If we fail and your symptoms are still severe, surgery may be considered.
