2. Manual Work
Manual work is actually also a common cause of tennis elbow. Anything that involves a lot of bending the elbow, or a lot of lifting large items with the elbows bent. If you lay bricks then or if you work on a construction site, this greatly increases your chances of developing the problem.
Another potential cause of tennis elbow is decorating and interior manual work. For instance, window cleaners and painters are likely to move their elbows in a very similar way, and this can likewise involve applying a lot of force and also using a repetitive motion for a long time consecutively. One way to reduce the likelihood of this leading to problems is to stretch and warm-up before getting started.
Finally, automotive work is also a likely candidate. That’s because you’ll be doing lots of twisting and bending while working on car engines and the like. Try to use different tools and take lots of breaks.
