Pain or numbness in the leg/genital area

Get the correct diagnosis on the sciatic nerve pain you’re experiencing
Piriformis Syndrome is more pervasive than many physicians realize. For example, in the United States each year, 1.5 million people have lumbar MRI scans to look for the cause of the buttock and leg pain called “sciatica.”
Yet more than 1.2 million of those scans fail to find the cause in the spine. Three hundred thousand of the scans are sufficiently positive that the patient has lumbar spine surgery. And of the 300,000 surgeries, as many as 25% fail to relieve the pain — in many cases because the diagnosis of a spinal cause for the sciatica was incorrect.
Piriformis syndrome also causes sciatica. Its treatment is much less invasive and severe than the treatment of herniated lumbar disks. However, many doctors never consider piriformis syndrome as a possible diagnosis. Many physicians who are aware of it are uncertain how to properly diagnose and treat it.
Dr. Aaron Filler credits the advent of MR Neurography and Open MR injection techniques with new large-scale outcomes as leading to the successful diagnosis and treatment of many more sciatica sufferers.

Meet Dr. Filler
A globally recognized expert in the treatment of peripheral nerve disorders and the development of nerve imaging technology, Dr. Aaron Filler is the world’s leading expert in treatment of nerve pain. He has revolutionized nerve-pain treatment by inventing several new technologies. One such technology, MR Neurography, enables doctors to use an MRI scanner to examine nerves, previously a difficult-to-impossible tissue to visualize with MR imaging.
Dr. Filler’s research in axonal transport is leading to a whole new generation of advanced pain medications. He has developed many new “minimal access” surgery methods that allow him to treat complex nerve problems with small outpatient surgeries. He has also pioneered the use of the Open MRI scanner to do surgeries and other therapies with the ultra-high precision and safety of the magnetic resonance imaging.
At Dr. Filler’s Neurological Injury Specialists Management Group in Santa Monica, California, the key to success remains a very traditional endeavor: listening to the patient and doing a thorough and expert neurological examination. Dr. Filler typically spends more than an hour with each new patient. The results of the initial examination are then strengthened and perfected with application of advanced technology available nowhere else in the world.
Dr. Aaron Filler combines three key components in his treatment of each patient:
- Compassionate personal attention,
- Expert medical skills, and
- The best technology in the world
He combines these components to turn insoluble pain problems into specific treatable diagnoses. Prior to coming to the Institute for Nerve Medicine, many of Dr. Filler’s patients have seen a dozen doctors (or more), experienced failed surgeries, and have even had their very pain questioned. Time and again, Dr. Filler demonstrates that in many of these cases the problem is the doctor and not the patient. A cure is in reach when the best available medical care is brought to bear.
Dr. Filler has an MD from the University of Chicago, a PhD from Harvard University, and is also a Fellow of the Royal College of Surgeons in England. His medical training included four years of medical school, eight years of neurosurgical training at one of the leading neurosurgery programs in the US, an additional one-year fellowship in neuroimaging at the University of London, another year of training in complex spinal surgery at UCLA, and a fellowship in peripheral nerve surgery with Dr. David Kline in New Orleans.
He is the inventor on ten major patents, has published more than twenty prominent scientific publications, and has done more than a hundred presentations at scientific and medical meetings. He is also the author of Do You Really Need Back Surgery? from Oxford University Press, a well-received 300-page book for the general public. He enjoys medical staff privileges at Cedars-Sinai Medical Center in Los Angeles.
