Arm and Shoulder Pain After Treatment

Breast cancer treatment—especially surgery and radiation—can impact how your arms and shoulders move and feel. It’s common to experience discomfort, stiffness, or limited mobility. While these side effects are often unavoidable, they can be treated and eased. The sooner you speak up about symptoms, the more support your care team can offer.

Why This Matters

About 60% of breast cancer patients report shoulder pain
Roughly 67% experience upper body weakness

Common symptoms include:

Numbness or tingling
Swelling
Weakness or stiffness
Limited range of motion
Pain or tightness

Although these issues can significantly impact daily life, they don’t have to be permanent.

What to Expect Over Time

1) After Surgery or Radiation

You may notice pain, numbness, or stiffness near your surgical or treatment site
It’s important to follow your doctor’s advice and wait for clearance before beginning movement or exercise
Your care team may recommend medication to reduce pain or inflammation

2) Early Recovery from Treatment

If cleared by your surgeon, you may begin gentle exercises or be referred to a physical therapist
Starting early can prevent long-term limitations in mobility
In some cases, rehabilitation specialists (like occupational therapists or physiatrists) can help you safely regain strength and function

3) Ongoing Recovery from Treatment

Strength and mobility return to normal for most individuals over time
Your doctor may refer you to a pain management specialist to consider medications or targeted injections if you have ongoing pain that is impacting your daily activities
In some cases, continued physical therapy or rehab exercises may be needed to rebuild strength and mobility
