Background: Hypereosinophilic syndrome is a rare disease that increases the number of circulating eosinophils in the body. It has many complications, including peripheral polyneuropathy. Peripheral polyneuropathy often does not respond well to conventional therapies. Transcutaneous neurostimulatory treatment, also known as scrambler therapy, is an alternative modality for the treatment of chronic retractable pain.
Case: A 47-year-old female presented with complaints of bilateral calf pain. She had been under treatment for peripheral polyneuropathy induced by hypereosinophilic syndrome for 7 years. Pharmacologic treatment did not affect the patient's symptoms.
Conclusions: Transcutaneous neurostimulatory treatment was administered to the patient. It was effective on her symptoms, and the effect of pain alleviation continued for 3 months.
