Testing an Herbal Pain Relief Patch to Reduce Pain in Cancer Survivors

The purpose of this study is to find out whether Tibetree Pain Relieving Plaster, an herbal pain relief patch, may be able to reduce this pain. Tibetree Pain Relieving Plaster is available as an over-the-counter (non-prescription) treatment for the temporary relief of minor aches and pains in muscles and joints. This study is the first to test this treatment in people who have had cancer.
