What to notice
Note whether discomfort occurs in the preparation, acceleration or follow-through. Extra practice buckets can matter even when the rest of the session feels easy.
Practical next steps
- Count practice serves as well as service games.
- Ask your coach to review the whole serving movement, not only the shoulder.
- Get persistent pain or weakness assessed before trying heavier strengthening work.
When to get help
Seek urgent assessment for sudden severe shoulder pain, a changed shape, inability to move the arm or persistent numbness. Arrange a review if pain keeps returning or does not improve.
