Measure
Scrambler
This arm will receive the Scrambler intervention for 1 hour daily x10 days. Scrambler: Scrambler is a non-invasive pain modifying technique that utilizes transcutaneous electrical stimulation of nociceptive fibers with the intent of re-organizing maladaptive signaling pathways which has been investigated for treatment of peripheral neuropathy.
Sham-Control
This arm will receive the Sham-Control intervention for 1 hour daily x10 days. Scrambler Sham Control: Sham control should be indistinguishable to the participants from experimental Scrambler therapy.

SECONDARY outcome

Timeframe: Baseline, 10 days

Population: Scrambler pre/post compared to sham pre/post using Wilcoxian signed rank

Change in NRS pain score (score ranges from 1 to 10 with 1 being "No pain" and 10 being "Worst pain") will be calculated by subtracting the patient's Day 10 pain score (end of treatment) from his or her baseline value.
