Strengthening the low back muscles can also be helpful. To start, lie on your front with your arms and legs extended in a straight line with your body. Raise your right arm and left leg. Put them down and raise your left arm and right leg. Put them down and continue.
Antiinflamitory medication can be helpful.
Ibuprofen, naproxin and aspirin are all available without a prescription. These drugs are most effective if they are taken early since inflamation is hard to get rid of once it's become established. A danger in antiinflamatory drugs is that they are also pain killers. Pain is your body's way of telling you that your doing damage. If you block the pain signals, you can easily aggravate your injury without knowing it.
