Have the ability to feel capsaicin-mediated sensations, as evidenced by ability to feel topically applied OTC capsaicin cream.
Are on a stable and continuous medication regimen, with no change in dosage for 21 days prior to study start, and are willing to maintain concomitant medications at current doses throughout the study.
Are willing and able to use oral opioid-based analgesic agents for relief, in case this is needed to relieve acute pain associated with the application of capsaicin patches.

You may not be if
Patients will not be eligible for this study if they:
Have diffusely distributed neuropathic pain (i.e., pain that is evident in more than 2 different sites). Subjects must not have significant pain outside the areas to be treated.
Have any implanted medical device (spinal cord stimulator, intrathecal pump or peripheral nerve stimulator) for the treatment of neuropathic pain.
Currently (within the past 21 days) use topically applied non-steroidal anti-inflammatory drugs, local anesthetics, steroids or capsaicin products on the painful areas.
Currently (within the past 21 days) use topical agents such as lidoderm patch 5%, topical steroids or aspirin.
Have a history or current problem with prescription drug or illicit substance abuse (from self report or as judged by investigator).
Currently have an abuse problem with alcohol (from self-report or as judged by investigator).
Are suspected of psychosocial gain/benefit of continued pain as judged by the investigator or primary treating physician.
Plan to travel more than 100 miles from home during the study or engage in unusual activities that might exacerbate pain.
Have poor cardiac, renal, hepatic, or pulmonary function judged by the investigator or primary treating physician.
Have a laboratory value at screening outside the normal range, unless it is judged by the investigator as not clinically significant after appropriate evaluation.
