Case in brief
A 26-year-old female presented with severe electric shock-like pain and hyperalgesia in her first toes following an ankle sprain, alongside symptoms of localized redness, swelling, burning sensation, and hyperhidrosis. Diagnosed with complex regional pain syndrome, she underwent ultrasound-guided pulsed radiofrequency treatment of the medial plantar nerve combined with platelet-rich plasma injection. One month post-procedure, her pain score decreased to 0, and autonomic symptoms resolved completely, with no recurrence noted during six months of follow-up.
Diagnostic / clinical pearl
Clinicians should consider ultrasound-guided pulsed radiofrequency combined with platelet-rich plasma injection as a potential treatment for complex regional pain syndrome when conventional pharmacotherapy fails.
