Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, possibility of
musculoskeletal pain is more. No need to worry for bladder related paint because bladder pain don't feel on upper right back, it usually feels on lower back.
You might have pulled muscle while playing tennis which is causing this pain.
So follow these steps for better symptomatic relief in musculoskeletal pain.
1. Avoid movements causing pain.
2. Avoid bad postures in sleep.
3. Avoid heavyweight lifting and strenuous exercise.
4. Apply warm water pad on affected areas.
5. Take painkiller and
muscle relaxant drugs.
6. Sit with proper back and chest support.
Don't worry, you will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
