Shoulder pain is a common complaint that can significantly affect daily life. Some of the most frequent causes include glenohumeral osteoarthritis, acromioclavicular (AC) joint osteoarthritis, and rotator cuff tendinopathy. Understanding these conditions — and the growing role of Platelet-Rich Plasma (PRP) therapy — can help patients make informed treatment decisions.
Today, we’ll break down what these conditions mean, how they’re usually treated, and how Platelet-Rich Plasma (PRP)— a natural therapy made from your own blood — is offering new hope for people wanting to stay active without heavy medications or surgery.
The glenohumeral joint is where the top of your arm bone fits into your shoulder blade.
Over time, the smooth cartilage protecting this joint can wear down.
Aching pain deep inside the shoulder
Difficulty lifting your arm or reaching behind your back
Grinding or popping sensations
Night pain
Modifying activities
Anti-inflammatory medications
Physiotherapy
Cortisone injections
Shoulder replacement surgery (in severe cases)
The AC joint connects the collarbone to the shoulder blade.
Even though it’s small, arthritis here can cause significant pain.
Pain on top of the shoulder
Pain with cross-body movements (like putting on a seatbelt)
Tenderness when pressing over the joint
Rest and activity adjustments
Ice therapy and anti-inflammatories
Cortisone injections
Minor surgery to remove part of the collarbone if necessary
The rotator cuff is a group of tendons keeping your shoulder stable.
When these tendons become irritated or degenerate, it leads to rotator cuff tendinopathy.
Dull ache on the outer shoulder
Weakness lifting the arm
Pain that worsens at night
Difficulty reaching overhead
Rest and gradual movement
Ice and heat therapy
Physiotherapy exercises
Cortisone injections if necessary
Surgery for large tears only
PRP therapy uses a small sample of your blood to promote healing.
After processing the blood to concentrate the healing platelets, the solution is injected into the injured joint or tendon.
Arthritis: PRP may reduce inflammation, relieve pain, and protect the joint.
Rotator cuff tendinopathy: PRP can encourage tendon healing and ease pain.
Performed as an outpatient procedure
Low risk since it uses your own blood
Results vary, but many patients see improvement over weeks to months
PRP isn’t a miracle cure, but it offers a promising natural tool for the right patients.
Shoulder arthritis and tendon problems can be life-limiting — but there are more options than ever.
Most patients manage their symptoms with a combination of rest, physiotherapy, and medications.
For those looking for alternatives, PRP therapy may offer a chance to heal naturally without relying heavily on steroids or surgery.
Discussing your options with a healthcare provider is the best way to create a personalised treatment plan that fits your goals and lifestyle.
