Is PRP Right for Your Shoulder?
If shoulder pain is making it hard to reach overhead, lift, get dressed, work out, or sleep on that side, platelet-rich plasma (PRP) is one option we use to support the tendons and joint — without jumping straight to surgery.
At Regenerative Medicine at UPC, Dr. Rainier Guiang, MD evaluates the likely pain source, your prior care, imaging if available, and your goals in a focused cash-pay consult before recommending whether a shoulder injection is reasonable.
We’ll be direct if PRP is unlikely to help, or if another evaluation (such as an orthopedic surgical opinion) should come first.
Who This Is For
Shoulder PRP is most often considered for:
Rotator cuff tendinopathy & partial tears
Pain reaching overhead or behind your back, or lying on that side.Full-thickness tears are evaluated case by case.
Shoulder arthritis
Wear-and-tear (glenohumeral or AC joint) pain and stiffness.
Bursitis & impingement
A painful arc when lifting the arm, often with a pinching feeling.
Biceps tendinitis
Pain at the front of the shoulder, worse with lifting or curling.
Frozen shoulder
Stiffness and pain from adhesive capsulitis.Evaluated case by case.
Tried the basics already
Activity changes, PT or other care, and want a candid, non-opioid option.
Who May Not Be a Good Candidate
PRP may not be right if you haveWe’ll tell you if that’s you
- A full-thickness, retracted rotator cuff tear, or sudden arm weakness after an injury Surgical opinion
- A fracture, dislocation or unstable shoulder needing urgent orthopedic care
- Advanced arthritis where joint replacement is already clearly indicated
- Active infection, certain blood disorders, or medical issues that make an injection unsafe
- Expecting one injection to guarantee a cure or fix the shoulder immediately
Why patients choose UPC
A physician-led, straight-talking approach:
What PRP Is & How It’s Made
PRP uses a concentrated portion of your own platelets, prepared in the office from a small blood draw and placed precisely in the shoulder with ultrasound.
Small blood draw
A small sample of your own blood is drawn from the arm at your procedure visit.
EmCyte PurePRP® centrifuge
The sample is spun in the EmCyte PurePRP® system to concentrate your platelets.
Ultrasound-guided injection
Dr. Guiang places the PRP at the tendon, bursa or joint under live ultrasound. Platelets release signaling proteins that may support the local healing environment.
PRP vs Cortisone for the Shoulder
Cortisone
- Can calm a flare quickly for some people
- Relief is often shorter-lived
- Repeated steroids may not be ideal for tendons over time
PRP
- Uses your own platelets — not a steroid
- Often chosen when the goal is longer-term tendon comfort and function
- Results vary by person and severity
How Long Does PRP Last?
Tendons heal slowly. Patients who respond usually notice gradual change over several weeks, alongside a rehab plan, and some do not improve. Results vary by diagnosis, tear size, and how long the problem has been present — we’ll set realistic expectations at your consult.

PRP for the Shoulder — FAQ
Is this the same as the insurance pain clinic?
No. Regenerative Medicine at UPC is our cash-pay regenerative department. Traditional insurance-based pain care is a separate practice, University Pain Consultants.
Can PRP repair a torn rotator cuff?
PRP cannot be promised to repair a tear. It may be considered for rotator cuff tendinopathy and some partial tears, along with rehabilitation. A full-thickness tear that has pulled back (retracted), or sudden weakness after an injury, usually needs an orthopedic surgical opinion first. We review your exam and any MRI or ultrasound and refer you when that is the better path.
Is PRP better than a cortisone shot for the shoulder?
They work differently. Cortisone can calm a flare quickly for some people, but relief is often shorter-lived and repeated steroid injections may not be ideal for tendons. PRP uses your own platelets and is not a steroid. Results vary, and we discuss both options at your consult.
Why is the shoulder injection ultrasound-guided?
The shoulder has several small, closely packed targets: rotator cuff tendons, the bursa, the biceps tendon sheath and the joint itself. Ultrasound lets Dr. Guiang see the target in real time and place the PRP where it is intended.
Can PRP help frozen shoulder?
Frozen shoulder (adhesive capsulitis) is evaluated case by case. Stretching-based physical therapy is usually central, and other injections may be considered first. We will tell you honestly whether PRP makes sense for your stage.
How soon will my shoulder feel better?
Some patients notice gradual change over several weeks, while others do not improve. Timing and degree of benefit vary, and a rehabilitation plan is usually part of the process.
What is the first step?
Book the complimentary 10-minute consult for a focused review of your shoulder, prior care and imaging, and an honest recommendation on whether PRP fits your problem and goals.
