Shoulder Muscles and Their Importance in Stability - #7041

I’ve been having some shoulder pain, and my doctor said it might be due to weak Shoulder Muscles. I had never thought much about them before, but now I’m wondering—what exactly are the Shoulder Muscles, and why are they so important?? From what I read, the Shoulder Muscles include the deltoids, rotator cuff muscles, trapezius, and pectoralis major. Each of these plays a different role in stability, rotation, and arm movement. But how do you know if your shoulder pain is from a muscle issue or something like a rotator cuff injury?? I also saw that weak or tight Shoulder Muscles can lead to shoulder impingement, frozen shoulder, and even posture problems. But what’s the best way to strengthen them? Do exercises like shoulder presses, lateral raises, and resistance band rotations help prevent injuries?? One thing I’m really curious about—why are Shoulder Muscles so prone to injury? I read that they have a wide range of motion but less stability, making them more likely to get strained. Are there specific stretches or mobility exercises that can help?? For those who have dealt with Shoulder Muscle pain, what was the cause, and what treatments or exercises helped the most??
