CIPN is a nerve problem and one of the potential side effects of chemotherapy that causes pain, numbness, tingling, swelling, or muscle weakness in different parts of the body. CIPN usually begins in the hands or feet and gets worse over time. SCS is a type of therapy that has proven to be effective in treating numerous non-malignant pain disorders including failed back surgery syndrome, refractory angina, limb ischemia, complex regional pain syndrome, and diabetic peripheral neuropathy. SCS may also be useful in patients with CIPN. This study evaluates how SCS affects pain and quality of life in patients undergoing spinal cord stimulation for CIPN.","PRIMARY OBJECTIVES:\n\nI.
