Shoulder Pain Q & A

About Shoulder Pain

The shoulder is a complex system of muscles, tendons, and joints that work to provide a range of motion to your arm. Unfortunately, this range of motion can also result in wear in the structure of your shoulder, causing stiffness and discomfort over time. Fortunately, you don't have to live with chronic shoulder pain and can receive treatment to return your mobility and provide relief for your pain.

Does My Shoulder Pain Need Surgery?

The most frequent fear of anyone with chronic shoulder pain is that they might need surgery to correct their condition. While this is certainly possible, the necessity of surgery is entirely dependent on the cause of your shoulder pain. Problems with the structure of your shoulder will often need surgery, while minor conditions may be treated by something as simple as a change in lifestyle.

Will I Have to Alter My Lifestyle?

A cause of shoulder pain that is incredibly easy to treat are injuries resulting from repetitive motion. Whether it's related to your job or a sports injury, repetitive, stressful movements can cause damage over time, causing stiffness and pain that limits your mobility. Restricting these activities or strengthening your shoulder with physical therapy are some of the many non-invasive treatments that can be used to address your shoulder pain.

What Does a Shoulder Exam Entail?

To get down to the bottom of your shoulder pain, your doctor will give you a comprehensive examination that can include a number of scans to determine your shoulder’s unique structure. These kinds of exams can be intimidating, which means you need a doctor you can trust.
