A right shoulder subluxation (partial dislocation) usually heals well with proper care, and many people recover completely over time. Rest, use of a sling if advised, and physiotherapy exercises are important to regain strength and stability. You can return to activities like swimming and badminton gradually, but only after pain has reduced and your doctor or physiotherapist clears you. Sleeping on the affected side may cause discomfort initially, so it is better to avoid it until the pain improves. If pain or instability continues, follow up with your doctor for further evaluation.
