Traditional Chinese medicine for foot pain in a patient with complex regional pain syndrome: A case report.

ABSTRACT

BACKGROUND: Complex regional pain syndrome (CRPS) is characterized by pain as well as sensory, motor, and sudomotor disorders. Generally, it is classified into two types CRPS-I and CRPS-II. There is no single diagnostic test or treatment approach for CRPS, and a multidisciplinary approach is gaining attention to improve patients' symptoms and their quality of life. CASE SUMMARY: A 35-year-old woman with an unremarkable medical history sought treatment for CRPS at a hospital of Korean medicine. During her first visit, she was wheelchair-bound due to severe pain in her left lower extremity. She had edema and discoloration of the left foot. She was treated with a combination of traditional Chinese medicine (TCM) approaches, including acupuncture, moxibustion, pharmacopuncture, and herbal decoction, for approximately 20 sessions. The foot and ankle outcome score (FAOS) and visual analog scale (VAS) score for pain were evaluated, along with general signs and functions. Her symptoms, signs, FAOS, and VAS scores improved after treatment, with a significant 7-degree decrease in the VAS score and a 62-point increase in the FAOS score. Additionally, the foot swelling and discoloration gradually resolved. During the phone follow-up, 5 mo after the last visit, additional improvements in outcomes were observed. CONCLUSION: Combined TCM treatment may be a reasonable and safe option for alleviating symptoms and improving function in patients with CRPS.
