My right shoulder popped out following a serve during a tennis match about 3 weeks ago. what kind of excersises should be done to strengthen it?

Physical Therapist: You need to consult with someone in sports medicine who can make the right exercise and precautions for you.

Varies: Do you mean you actually dislocated it? Generally strengthening exercises done while also avoiding redislocation would be done. Ideally this would be directed by s physical therapist and done only after a detailed exam to check for any ongoing instability.

Evaluation: You should get your shoulder seen by an orthopedic surgeon. However, in general, you need to do rotator cuff strengthening exercises and scapular stabilization exercises for shoulder instability.
