If shoulder pain is left untreated, it can lead to further complications and cause more serious issues. These issues may include chronic instability, increased risk of re-injury, decreased range of motion, muscle weakness, and fatigue. Therefore, it is important to seek medical care early on for the best chance at a successful treatment plan. The best way to prevent reinjury is to follow the treatment plan that your doctor develops for you. This includes taking all medications as prescribed, participating in physical therapy, and performing the exercises at home, to strengthen the muscles around your shoulder joint.  Additionally, it is important to avoid activities that put too much strain on your shoulder until it has had time to heal properly. If you are unsure of what exercises or activities are safe for you to do, always consult with a doctor before engaging in them.
