Hands swollen and painful after gardening

I often help my elderly sister with her housework. Last time I visited, I noticed that the path was becoming overun with sprawling rose bushes from the nearby garden bed. I spent over one hour cutting them back. That night my hands were swollen and very painful. I could not have got through the night without the help of my jar of Simply Flower Power cream. I applied it frequently throughout the the night and each time the pain would reduce substantially.
