I suffer from degenerative disc disease. Over the past few years my back has gotten worse and worse...
I have three herniated discs, two in the lumbar region. This causes sciatica and much local pain. I find if I stretch regularly, keep loose, and don't abuse my back, I can avoid flare-ups. When I do get flare-ups, I have to rest (bed-rest, no hiking, no exercise) until the acute pain resolves and then slowly rehab with stretching and core exercise.
Over the past two years the situation has become increasingly worse, with flare-ups happening more frequently and being more severe.
I've seen several orthopedic docs/surgeons, and they all have the same advice. They first prescribe PT to loosen muscles and to strengthen core muscles to stabilize the spine and protect the site of injury. This is what they call "conservative" treatment. Once PT becomes insufficient to remedy the problem, the next course of action is steroid injections in the spine, as mentioned above. They help some people more than others, but the fix is not permanent. Once the injections fail to work you are left with fewer options.... Pain management (opiates etc etc) or surgery. In the disc compresses motor neurons to the point of muscle atrophy, surgery is often mandatory.
I am currently struggling with the thought of a discectomy, but would like to avoid it if possible. All my family are against surgery and are VERY vocal about it. That said, my condition will tends to get worse with time (degenerative disc disease), and I fell that surgery is inevitable for me. I have an apt for steroid injections early next month. Hopefully they will help long enough for me to do some strengthening and to avoid or at least delay the discectomy for a few more years...
I have a few friends who have had discectomy and they benefit, but they all have had a LONG road to recovery and some will probably never get back to where they once were. A lot depends on the physical condition you are in before you go through with surgery...
I should also mention that I beat the hell out of my back during all 4 seasons, am very stubborn, and don't listen too closely to what I am told. Soooo, my case may be worse than the average persons.
