Compare Ultrasound Assisted Cold Therapy and Lidocaine Injection to Treat Morton's Neuroma

The purpose of this study is to evaluate the effectiveness of a device that delivers freezing temperature compared to injecting lidocaine (an anesthetic medication) in providing pain relief to patients with disorganized nerve bundle between the toes, also known as Morton's neuroma. The same ultrasound technology that the obstetricians use to visualize a fetus inside a pregnant woman will be used to help the study physician to locate the Morton's neuroma while precisely delivering the freezing temperature and lidocaine near the nerve.
