COOLIEF* Non-Surgical Treatment for Relief of Chronic Pain

[Sparta, New Jersey – 19 August 2014] – Pain specialist, Richard Siegfried, MD today announced the availability of COOLIEF* Cooled Radiofrequency Treatment, a non-invasive, outpatient option for those suffering from chronic back, hip or knee pain at their offices in Sparta, NJ and Milford, PA.

Dr. Siegfried’s practice is one of the first in Sparta, NJ and Milford, PA to offer the COOLIEF procedure which is designed to treat pain lasting for longer than three months. The minimally invasive, outpatient procedure uses cooled radiofrequency (RF) energy to safely target the sensory nerves causing pain. COOLIEF circulates water through the device while heating nervous tissue to create a treatment area that is larger than conventional RF treatments. This combination targets the pain-causing nerves without excessive heating, leading to pain relief.

Most patients with chronic back, hip or knee pain try managing their symptoms with oral anti-inflammatory medications, steroid injections and physical therapy, while others have tried standard RF ablation and fusion procedures. Clinical Studies have demonstrated that cooled radiofrequency treatment can provide up to 24 months of relief from chronic back pain,2. Most patients experience pain relief and improved mobility and are able to return to their normal activities within a few weeks.

“Chronic pain is a life altering physical and emotional problem that is often very resistant to treatment. Many of my patients suffering from low back pain or hip pain or knee pain have tried a variety of treatments to ease their symptoms including injections and surgery but have

experienced limited or no lasting pain relief. We also now know that the long-term use of narcotic pain medications is absolutely not a safe, effective and sustainable strategy for treating chronic pain,” said Dr. Richard N. Siegfried. “COOLIEF is a safe and effective treatment option that delivers long-lasting pain relief for many patients and helps them to get back to enjoying their everyday lives. We are excited to be one of the first practices in the area to offer our patients this treatment for relief from pain.”
