I just wanted a bit of advised regarding doing repetitive work. I have osteoarthritis in both my hands and wrists. My right shoulder is now starting to give me trouble. I work in the family business. I wash and put new wraps on commercial freezers. This means I am constantly using my hands and a right to left movement in my arm as I complete tasks. The level of pain in my hands and swelling is definitely getting worse over time. I know it good to completed hand etc flexible and fit. However, I wanted to know if I am making my own situation worst by my work actions.
