Frequently Asked Questions

What is supraspinatus tendinitis?

Supraspinatus tendinitis is inflammation of one of the main rotator cuff tendons on the top of the shoulder. This tendon helps lift the arm and stabilize the joint. When irritated, it can cause pain and weakness.

What causes supraspinatus tendinitis?

It is commonly caused by repetitive overhead activity, overuse, or poor shoulder mechanics. Sports like swimming, tennis, and baseball increase the risk. Age-related changes can also contribute.

What are the symptoms?

Symptoms include shoulder pain, especially when lifting the arm or reaching overhead. Pain may worsen at night or when lying on the shoulder. Some people notice weakness or limited motion.

How is it treated?

Treatment includes physical therapy, activity modification, and anti-inflammatory medications. Strengthening and improving shoulder mechanics are important. Injections may be used if symptoms persist.

When can I return to activity?

Most patients improve over several weeks with proper treatment. Return to activity depends on pain-free motion and strength. Gradual progression is important to prevent recurrence.
