Complex Regional Pain Syndrome

Complex regional pain syndrome (CRPS), previously known as reflex sympathetic dystrophy (RSD), is a malfunction of the nerves and nervous system that can cause severe pain, swelling, loss of range of motion, temperature changes, and changes in the skin. CRPS is a severely disabling condition that usually affects the limbs, after injury, surgery or stroke.

A diagnosis is made based on excluding other causes, a thorough history and physical exam, nerve conduction studies, and imaging studies (Bone scan, X-ray, CT, MRI). The exact cause of CRPS is unknown. It may be a disorder of the immune system that affects the nervous system, producing inflammation of the nerves that control blood flow, sensation, and temperature.

Complex Regional Pain Syndrome Treatments

CRPS treatment is most effective when started early and focuses on retaining range of motion, slowing the progression of the disease, and helping cope with the pain and lead as healthy lives as possible. Medication, psychological support, injections, nerve blocks, spinal cord/nerve stimulators, and surgery may be part of your treatment.

What Our Patients Are Saying...

Slide 3

I’ve been a patient of Dr. Derrick Wansom for several years. I have multiple issues that cause me major pain. He has always managed to keep me comfortable. He is a quiet, patient man…… always listening to me, & I’ve never been rushed. He asks appropriate questions, & then gives me my options. He has a nice new office with most of his services conveniently available on site. If you need a good Pain Management physician that genuinely cares, he’s the one!

I was referred to Dr. Sarna by my primary care doctor who felt I needed someone who was compassionate, and very skilled. The other groups I have been too were usually missing one, if not both, of these criteria. Dr. Sarna fit the bill for both. After years of pain management doctors with little success I finally got relief from my neck pain with some specific, and fairly easy – for me – injections. They actually worked. I credit this success to the expertise, knowledge, and skill level of this doctor. Would definitely recommend this physician as the best!

Dr Sarna is superior in his skills, knowledge, and bedside manner. He helped me in an urgent situation and took excellent care of me throughout my treatment. He really does care about you as a patient. He discussed thoroughly my options, then helped me make the right choice for me. I am a RN and very picky about choosing doctors and other providers.

Delighted that Dr. Wansom is opening at a new location! Looking forward to further treatment for a veteran friend of mine. Do you know when you can hear someone smiling through their voice over the phone? When I called for an appointment, the gal in the office was delightful and helpful in answering questions and navigating with insurance. Looking forward to the next treatment with Dr. Wansom at the new location. It is so great to find alternative therapies to back pain which is not driven with pills.

The facilities were very nice and clean, the staff and front desk person was very friendly and personable. Dr. Wansom and his new practice is the best that you will find in the Austin, San Antonio and all areas in between that you will find.
