Brief Summary

This is a research study of SP-102, an experimental medication designed to relieve pain in patients with a specific type of leg pain. The mediation is given once by your healthcare professional, with a possibility of a second injection as early as about 1 month after the first treatment.

The purpose of the study is to measure how well a single injection of the experimental medication, SP-102, relieves pain. The study will also investigate the side effects of SP-102.
