Manual workers. If you do a lot of heavy lifting or repetitive motion on the job, it can strain your joints and bring on bursitis.
Athletes. We're not only talking about professional players here. Even if you're just a weekend warrior, you can get bursitis after running, throwing, jumping, or making aggressive arm swings in tennis, baseball, and even bowling.
Couch potatoes. No, you won't get bursitis from sitting on the sofa watching TV. But if you're out of shape and push your body too hard during exercise, you can raise your chance. Always start a new workout routine slowly.
