Hi there
I am a trained Osteopath and understand a bit of what you are saying therefore I can tell you that yes you should not stop doing something for some herniated discs. First of all you should think what are the likely causes that have made the discs to bulge.
Normally a disc has its problems whan subjected to too much weight hence if you are overweight try to lose some it will definetly help. Then when you are choosing a rocksack you should take one that sits well on your hips so that the extra weight of your bag is not going through the spine but it goes to the hips and then legs. There are some places on the net or forums that can help you adjusting your bag.
Then it is of vital importance that the muscles that brace your back (especially abdominis transversus) are well toned so that your belly is not bulging out carrying with it the back forward. Simple pilates classes can really make the difference. This will help you with your core stability muscles most probably getting rid of your back pain and making your sex life better!
Second smoking damages the fibers of the disc making it less strong. At night when you sleep the disc absorbs fluid and during the day, when under pressure it releases fluid. Make sure you drink plenty of water when you walk this will help keep the disc hydrated hence more able to take abuses from the ground force and weight.
When you put your bag on your shoulder make sure that you are not putting directly on your back as an act of bravery instead try to either put the bag first on a table or ask someone to help you. It is torsion movements that causes the disc to get more damaged. So the less you turn around when you are lifting weights the better it is.
