Back Pain
Your back includes the area from below your neck to your tailbone. It is composed of the bones of the spine (vertebrae); the joints that guide the direction of movement of the spine; the discs that separate the bones of the spine and absorb shock as you move; and the muscles and ligaments that hold them all together. One or more of these structures can be injured.

| A spinal disc that bulges or ruptures can put pressure on a nerve, causing pain. |

Overuse or a sudden or improper movement can result in strain or sprain of the spinal ligaments, the muscles in the back, or the sacroiliac joints (the joints between the spine and either side of the pelvis). You can damage your discs the same way so that they tear, stretch, or rupture.

If the tear is large enough, the jelly-like material inside the disc may leak out and press against a nerve. The nerve may also become irritated due to swelling or inflammation in other parts of the back.
Any of these injuries can result in 2 or 3 days of acute pain and swelling in the injured tissue, followed by slow healing and a gradual reduction in pain. The pain may be felt in the low back, in the buttock, or down the leg (this type of pain is called sciatica). The goals of self-care are to relieve pain, promote healing, and avoid reinjury.
Back pain can also be caused by conditions that affect the bones and joints of the spine. Arthritis pain may be a steady ache, unlike the sharp, acute pain of strains, sprains, and disc injuries. If you think your back pain may be caused by arthritis, combine the self-care guidelines for back pain with those for arthritis on See Home Treatment.
Osteoporosis weakens the bones of the spine, which can lead to compression fractures. Compression fractures cause vertebrae to collapse. This can cause misalignment of the spine, which may put pressure on the discs and spinal nerves and lead to varying degrees of pain.

Sciatica is an irritation of the sciatic nerve, which runs from the lower back down through the buttocks to the feet. Sciatica can occur when an injured disc presses against the sciatic nerve. Its main symptom is radiating pain, numbness, or weakness that is usually worse in the leg than in the back. In addition to the Home Treatment for back pain on, the following may help:

Prevention |
The keys to preventing back pain are to use good body mechanics and to practise good health habits, such as getting regular exercise, avoiding
tobacco, and maintaining a healthy body weight. Some of the tips presented in this chapter are things you will want to do every day, not only because they are good for your back, but because they are good for your overall health. The rest will come in handy if you are ever suffering from acute back pain.
|
Body Mechanics |
Good body mechanics will reduce the stress on your back. Use good body mechanics all the time, not just when you have back pain.
|
Sitting |
If you must sit a lot, the exercises on See Extension Exercises See Hip flexor stretch (shading shows where stretch is felt) are particularly important.
|
Exercise |
Regular exercise (stretching, strengthening, and aerobic exercise) helps you maintain your overall fitness and flexibility and strengthens the muscles that support your spine. Exercising also helps you maintain a healthy body weight, which reduces the load on your lower back. If you are interested in creating a personalized fitness plan, see Fitness.
Although there is no clear evidence that specific exercises can help prevent back pain, the exercises presented here are a common, practical approach to helping you maintain strength and flexibility. You may choose to make the exercises a part of your regular fitness routine. If you never do them until you experience back pain, they will help you feel that you are doing something positive to take charge of your body.
Do not do these exercises if you have just injured your back. Instead, see "First Aid for Back Pain" on See First Aid for Back Pain When you first feel a catch or strain in your back, try these steps to avoid or reduce pain. These are the most important Home Treatments for the first few days of back pain.
Extension exercises strengthen your lower back muscles and stretch the stomach muscles and ligaments. Flexion exercises stretch the lower back muscles and strengthen the stomach muscles.
|
Extension Exercises |
Begin and end every set of exercises with a few press-ups.
Shoulder lifts will strengthen the back muscles that support the spine.
|
| Shoulder lifts (keep neck straight and chin down) |
|---|
Practise the backward bend at least once a day and whenever you work in a bent-forward position.
|
Flexion Exercises |
Curl-ups strengthen your abdominal muscles, which work with your back muscles to support your spine.
Slowly curl your head and shoulders up until your shoulder blades barely rise from the floor. Keep your lower back pressed to the floor. To avoid neck problems, remember to lift your shoulders, and do not force your head up or forward. Hold for 5 to 10 seconds (do not hold your breath), and then curl down very slowly.

| Curl-ups (keep neck straight and chin tucked in) |

The knee-to-chest exercise stretches the lower back and hamstring muscles (in the back of the thigh) and relieves pressure on the joints where the vertebrae come together.
This exercise strengthens the buttocks muscles, which support the back and help you lift with your legs. You may need to place a small pillow under your stomach for comfort.
See instructions on See First Aid for Back Pain When you first feel a catch or strain in your back, try these steps to avoid or reduce pain. These are the most important Home Treatments for the first few days of back pain.
This exercise stretches the muscles in the back of your thigh, which will allow you to bend your legs without putting stress on your back.
This exercise stretches the muscles in the front of your hip.
Slowly sink your hips so your weight shifts onto your front foot. The knee of your forward leg should be aligned over the ankle. Hold for 10 seconds. You should feel a stretch in the groin of the leg you are kneeling on. Repeat with the other leg.

Exercises to Avoid |
Many common exercises actually increase the risk of low back pain. Avoid the following:
Home Treatment |
Immediately after an injury and for the next few days, the most important Home Treatment includes the following:
Follow the "First Aid for Back Pain" guidelines on See First Aid for Back Pain When you first feel a catch or strain in your back, try these steps to avoid or reduce pain. These are the most important Home Treatments for the first few days of back pain. Also see Home Treatment on page 114..
For bed rest, try one of the following positions (see illustrations on Try placing pillows between or under your knees to relieve back pain while lying in bed.):
Take aspirin or ibuprofen regularly as directed. Call your doctor if these medications cause stomach pain or make your stools look black. Acetaminophen may also be used. Take these medications sensibly; the maximum recommended dose will reduce the pain. Masking the pain completely might allow movement that could lead to reinjury.
After 2 to 3 days of Home Treatment:
When your pain has improved, begin easy exercises that do not increase your pain. One or 2 of the exercises described on See Exercise See Hip Flexor Stretch may be helpful. Start with 5 repetitions 3 to 4 times a day and increase to 10 repetitions as you are able.

When to Call a Health Professional |
If you have new or increased back pain with unexplained fever, painful urination, or other signs of a urinary tract infection. See Urinary Tract Infections.
If back pain does not improve after 2 weeks of Home Treatment.

Your Family Doctor |
In addition to diagnosing the cause of back pain and evaluating back injuries, a doctor may also:
|
Physical Therapists |
After the initial first aid treatments, a physical therapist with training in orthopaedic treatment can:
|
Other Health Professionals |
Chiropractors and osteopaths can provide relief from some types of back pain through spinal manipulation. Spinal manipulation usually works best if you have had symptoms for fewer than 4 weeks. If your symptoms don't improve after 1 month of spinal manipulation treatment, stop the treatment and have your pain reevaluated.
Acupuncturists, massage therapists, and others can also provide treatments that may give short-term relief. For more information, See Complementary Medicine.
