Well, if the slipped disc or
herniated or protruded
disc is not going back in place, you may need
surgery. However, you could try spinal manipulation, traction, physiotherapy, back exercises etc along with pain killers to see if it is helping the disc fall back in place. If your symptoms decrease appreciably by these measures then you may not need surgery.
However, you will need to avoid strenuous activities, lifting and pushing heavy things, high impact sports etc.
