Why is this study being done?

The purpose of this study is to examine the short- and long-term efficacy of botulinum toxin type-A (BOTOX®, Allergan, Inc.) in treating pain caused by damage to a nerve. Participants will receive either Btx-A or placebo (sterile saline injection).

Who is eligible to participate?

Males and females, 18-90 years of age with neuroma pain.

What is involved?

Participants will be randomized and given either BOTOX® or a placebo (saline) at the first appointment.

How long is the study?

The study is a long-term follow-up study in which the participants will be contacted several times over 5 years to see how long the effects of BOTOX® injection(s) last.
