Try conservative measures first to control pain, and know the limits and risks of this therapy if you choose to try it.
Most men who suffer from back pain already know the drill: time heals this wound. Over weeks to months, the pain will calm down, and you will slowly return to your normal life. In the meantime, try to stay as active as possible and rely as much as possible on over-the-counter pain relievers.
But for some men, these conservative measures may not relieve the agony soon enough—especially if the problem is back pain caused by irritated spinal nerves. After a few weeks, just getting to the bathroom may start to feel like Napoleon's winter march to Moscow. At that point, you may be offered an injection of a steroid medication to calm the war zone in your lower back.
Even for nerve-related back pain, guidelines discourage hasty intervention with steroids. "You would do less invasive, less aggressive things first," says Dr. Robert Shmerling, an associate professor of medicine at Harvard-affiliated Beth Israel Deaconess Medical Center.
However, if you choose this therapy, know its limits. "The shots are almost always a temporary measure," Dr. Shmerling says. "In general, it's for symptom control, and not a definitive treatment for most conditions."
Used appropriately, steroid injections can calm inflamed joints and tissues but do not speed healing or prevent future problems. Here are some of the most common targets for steroid injection therapy:
What is conservative therapy?
Steroid injections are not for ordinary strain-and-sprain backaches. Orthopedic specialists usually offer it for shooting nerve pain (sciatica) from a ruptured disk, or symptoms associated with narrowing of the space around the spinal cord (spinal stenosis).
Even for nerve-related back pain, try the conservative route first, because steroid shots come with risks. Conservative therapy includes the following:
To control pain, first try nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil, Motrin), naproxen (Aleve), and plain old aspirin. If that doesn't work, ask your doctor about other medications for nerve-related pain. Narcotic pain relievers should be used only for the short term, if at all. These include hydrocodone (Vicodin) and oxycodone (OxyContin, Percocet).
Keep moving as much as you can manage. Short periods of bed rest may be helpful during the acute phase, but extended bed rest isn't.
How long should you wait before considering injection therapy? It depends on the intensity of the pain and how long you can bear it before it starts to ease on its own. Most men experience substantial improvement in six to eight weeks.
How steroid shots work
Steroid injections contain various formulations of medications. A common combination is the numbing drug procaine hydrochloride—known to millions of dental patients as Novocain—mixed with the anti-inflammatory drug cortisone.
Once the injection finds its target, the numbing effect will start to wear off within hours. "As the Novocain wears off, the pain may temporarily come back," Dr. Shmerling says. "Then 24 to 48 hours after the injection, you can begin to expect whatever benefit you're going to get."
What to expect
If the injection works, you'll certainly be grateful for the relief, but success is not guaranteed. In studies of large groups of back pain sufferers, the benefit is small to none on average. It's hard to predict what you, individually, will experience.
Steroid injections do not change the course of a chronic back pain condition. Months down the road, you will generally end up in the same condition as if you never got the shot. In the meantime, the shot could ease your discomfort.
Steroids have risks
Harmful side effects of injections are uncommon, but they do happen. The main risk is infection, which occurs less than 1% of the time. Less commonly, the needle could injure a nerve or blood vessel.
Having too many injections in the same target area can cause nearby tissues, such as joint cartilage or bone, to break down. Steroids can also cause skin at the injection site or the soft tissue beneath it to thin. This is why it's recommended to limit the number of injections to three or four per year at any body region treated.
