How is Sciatica Diagnosed?
A medical history should be taken, and your physician should give a physical examination. The straight leg raise test is great to help diagnose a sciatica case. This test can determine the spinous process level, where the pathology may exist. Next, your practitioner may prescribe x-rays to search for any spinal fractures.
Magnetic resonance imaging (MRI) is used to look in detail at soft tissue structures for any pathology
Electromyography or nerve conductivity velocity testing (NCV) can be used to determine the rate at which the nerve impulse can travel through the sciatic nerve. A myelogram can be ordered to look for spinal pathology in a more detailed fashion. An injectable contrast dye goes into the spine while an x-ray is performed.
What is the Conventional Treatment for Sciatica?
Most often, after examination by a physician, the sciatica patient may be referred to physical therapy
This first level of treatment for sciatica is non-invasive. It will usually consist of ice and heat therapy, stretching of the nerve and surrounding tissue with exercises to strengthen the surrounding regions. In the past, bed rest was given as a therapy for sciatica. In contrast, today, patients are advised to keep moving, walking, swimming, and exercising.
The next level of therapy may consist of medication, such as non-steroidal anti-inflammatory drugs (NSAIDS). Muscle relaxants such as Flexeril may be prescribed if the over the counter drugs are not effective.
A spinal injection may be performed. This is an injectable corticosteroid to drop the inflammation down, bring pain relief, and increase mobility.
Finally, there are the surgical options which may include a microdiscectomy or a laminectomy. Both procedures surgically remove either bone structure or bony fragments that may impinge into the sciatic nerve root, causing inflammation and pain.
