Effects of Pennsaid on Clinical Neuropathic Pain
The purpose of this study is to see if the drug Pennsaid (Diclofenac) can help reduce pain felt by people with chronic nerve pain. The drug will be used 2-4 times each day for 2 weeks. The U.S. Food and Drug Administration (FDA) has approved Pennsaid to treat osteoarthritis (bone pain), but the FDA has not approved Pennsaid to treat neuropathic (nerve) pain. The research study will compare Pennsaid to placebo.
