Shoulder pain can come from many different problems, but two common causes are rotator cuff tendinopathy and shoulder arthritis. These conditions can feel similar because both can cause pain, stiffness, and trouble using your arm. However, they affect different parts of the shoulder.
What Is Rotator Cuff Tendinopathy?
The rotator cuff is a group of muscles and tendons that helps move and steady the shoulder. These tendons help you lift your arm, reach overhead, throw, push, pull, and do many everyday tasks.
Rotator cuff tendinopathy means the tendon is irritated, overused, or not healing well. This does not always mean the tendon is fully torn. Many people with this condition have pain from tendon inflammation, tendon wear, or small changes in the tissue over time.
Rotator cuff tendinopathy may cause:
- Pain when lifting the arm
- Pain reaching behind the back
- Pain when lying on the affected shoulder
- Weakness with certain movements
- A dull ache in the upper arm or outside of the shoulder
This type of shoulder pain is often related to overuse, aging, sports, work tasks, poor shoulder mechanics, or repeated overhead motion.
What Is Shoulder Arthritis?
Shoulder arthritis is different. Arthritis affects the joint, not just the tendon. A healthy shoulder joint has smooth cartilage that helps the bones glide easily. With arthritis, that cartilage can wear down over time.
When the joint surface becomes rough, movement may become painful or stiff. Some people also feel grinding, clicking, or deep aching inside the shoulder.
Shoulder arthritis may cause:
- Deep joint pain
- Stiffness
- Limited range of motion
- Pain that gets worse with activity
- Grinding or catching sensations
- Trouble sleeping due to aching
Arthritis is often linked to aging, past injury, joint wear, inflammation, or certain medical conditions.
What Is PRP?
PRP stands for platelet-rich plasma. It is made from a small sample of your own blood. The blood is placed in a machine that separates and concentrates the platelets. Platelets are blood cells that play a role in clotting and healing. PRP contains growth factors that may support the body’s natural repair process.
After PRP is prepared, it is injected into the area being treated. For shoulder pain, this may be around a tendon, into a joint, or near irritated tissue, depending on the diagnosis and the provider’s plan.
How PRP May Help Rotator Cuff Tendinopathy
For rotator cuff tendinopathy, PRP is often used with the goal of supporting tendon healing. Tendons can be slow to heal because they do not have as much blood flow as some other tissues. PRP may help by bringing a higher concentration of healing-related factors to the irritated tendon area.
In simple terms, PRP may help “remind” the body to work on healing the tendon. It may help reduce pain and improve function for some people, especially when tendon irritation has not improved with rest, physical therapy, or other conservative care. Research on PRP for rotator cuff tendinopathy is still mixed, and experts note that more consistent evidence is needed.
How PRP May Help Shoulder Arthritis
For shoulder arthritis, PRP is used for a different reason. Since arthritis involves joint wear, PRP does not rebuild a brand-new joint. It is not a cure for arthritis.
Instead, PRP may help some people by calming irritation in the joint and supporting a healthier joint environment. The goal is usually pain relief, better movement, and improved daily comfort. Some providers use PRP as a nonsurgical option for people trying to manage arthritis symptoms before considering more invasive treatments.
Wondering If PRP Could Help Your Shoulder Pain?
With rotator cuff tendinopathy, PRP is usually aimed at the tendon.
With shoulder arthritis, PRP is usually aimed at the joint.
Both conditions can cause shoulder pain, but they’re not the same problem. That’s why getting the right diagnosis matters. A medical provider may use an exam, X-rays, ultrasound, or MRI to better understand what’s causing your shoulder pain, whether that’s rotator cuff tendinopathy, shoulder arthritis, or something else entirely.
PRP may help some people with shoulder pain caused by rotator cuff tendinopathy or arthritis by supporting the body’s natural healing process and helping reduce irritation in the affected area. However, results vary. It is always best to talk with a qualified medical provider about your symptoms, diagnosis, treatment options, risks, cost, and whether PRP may be a reasonable choice for your shoulder pain.
