Initially, the doctor may recommend some bed rest, cold therapy, and medications. Bed rest takes the pressure off nerves in the low back. During the first 24 to 48 hours cold therapy helps to reduce swelling, muscle spasm, and pain by reducing blood flow. These work by relieving both swelling and pain. Usually, after the first 48 hours, heat therapy can be applied.
Heat increases blood flow to warm and relax soft tissues.
Increased blood flow helps to flush away irritating toxins that may accumulate in tissues as a result of muscle spasm and disc injury. If leg pain is severe, or leg weakness is developing, the doctor may prescribe an epidural injection. An epidural is an injection of anti-inflammatory medication into the space near the affected nerves. You should discuss this option with your doctor and ask about potential side effects before beginning this treatment. The doctor may recommend physical therapy.
