# What do people ask about shoulder soreness? *Shoulder regeneration Gilbert | Common Questions* > Shoulder regeneration Gilbert answers on common causes, simple home help, PRP, warning signs, visits, and the Chandler clinic. This page answers common shoulder questions. You'll find home help, warning signs, and office choices. Each answer stays focused on your next step. An exam may change the answer. Tendons, the cords joining muscle to bone, can hurt. That soreness differs from joint wear. ## Sources 1. A concise review of mesenchymal stem cells for functional cartilage tissue engineering sets out the underlying problem: articular cartilage is avascular and has very limited intrinsic repair capacity, which is precisely why engineered and cell-based approaches are being pursued - and why building tissue that matches native articular cartilage in composition and mechanical function remains an unsolved engineering problem rather than a delivered clinical product. Tan AR, et al. — [Concise Review: Mesenchymal Stem Cells for Functional Cartilage Tissue Engineering: Taking Cues from Chondrocyte-Based Constructs.](https://pubmed.ncbi.nlm.nih.gov/28177194/). *Stem cells translational medicine*, 2017. DOI: 10.1002/sctm.16-0271. 2. The RESTORE trial - a participant-, injector- and assessor-blinded RCT of 288 adults aged 50+ with symptomatic medial knee OA (Kellgren-Lawrence 2-3) - compared three weekly intra-articular PRP injections against saline placebo, with co-primary endpoints of 12-month knee pain and medial tibial cartilage volume on MRI. PRP did not beat placebo on either. It is the single best-designed test of the specific claim that PRP changes joint structure, and it was negative. Bennell KL, et al. — [Effect of Intra-articular Platelet-Rich Plasma vs Placebo Injection on Pain and Medial Tibial Cartilage Volume in Patients With Knee Osteoarthritis: The RESTORE Randomized Clinical Trial.](https://pubmed.ncbi.nlm.nih.gov/34812863/). *JAMA*, 2021. DOI: 10.1001/jama.2021.19415. 3. A four-arm, multicentre, single-blind phase 2/3 randomized trial of 480 knee OA patients (KL II-IV) compared autologous bone marrow aspirate concentrate, autologous adipose stromal vascular fraction and allogeneic umbilical-cord-tissue mesenchymal stromal cells against a corticosteroid injection control. At 12 months NONE of the three orthobiologic injections was superior to another, or to the corticosteroid control, and none of the four groups showed a significant change in MRI osteoarthritis score from baseline. No procedure-related serious adverse events occurred.

DOI: 10.1038/s41591-023-02632-w. 4. FDA states plainly that no stem cell, exosome, stromal vascular fraction, umbilical cord blood, Wharton's jelly or amniotic-fluid product has been approved for the treatment of ANY orthopedic condition - it names osteoarthritis, tendonitis, disc disease, tennis elbow, back pain, hip pain, knee pain, neck pain and shoulder pain individually. The only FDA-approved stem cell products in the United States are cord-blood-derived blood-forming stem cells for disorders of the hematopoietic system, and there are currently no FDA-approved exosome products.

In the MOON Shoulder prospective cohort of 452 patients with symptomatic, ATRAUMATIC full-thickness rotator cuff tears, physical therapy succeeded in more than 70% of patients at 10 years: only 115 (27.0%) had surgery at any point over the decade. Patient-reported outcomes improved with physical therapy and did NOT decline over 10 years in those who never had surgery. The strongest predictor of early surgery was low patient expectation of physical therapy, not tear anatomy.

DOI: 10.2106/JBJS.23.00978. 6. A 2025 systematic review of 1,125 patients receiving intra-articular injections for glenohumeral osteoarthritis reported a 7.2% overall complication rate and a 3.2% rate of proceeding to surgery. Hyaluronic acid showed consistent though modest benefit, while the evidence for ORTHOBIOLOGICS (PRP, bone marrow aspirate concentrate, mesenchymal stem cells) 'remains limited', mainly because of heterogeneity in design, outcomes and patient characteristics. Migliorini F, et al. — [Intra-articular injections for shoulder arthritis in adults: a systematic review.](https://pubmed.ncbi.nlm.nih.gov/41204311/). *Eur J Med Res*, 2025.

In a nationally representative Finnish population sample of 602 adults aged 41-76 who had bilateral 3-Tesla shoulder MRI regardless of symptoms, rotator cuff abnormalities were found in 98.7% of participants (25% tendinopathy, 62% partial-thickness tear, 11% full-thickness tear). Abnormalities were present in 96% of ASYMPTOMATIC shoulders. Only full-thickness tears were more common in symptomatic shoulders, and that difference all but disappeared after adjustment (absolute difference 0.8%, 95% CI -3.4% to 6.0%).

Repeated reaching can slowly raise the soreness. Arthritis may bring stiffness and a deep ache. An exam can sort these causes when rest doesn't help. ## What can I do at home for shoulder soreness? Use the sore movement less for now. Don't keep testing sharp pain. Gentle movement can help you stay loose. Add strength only as the soreness settles. Get advice if the pain keeps climbing. ## When does shoulder soreness need urgent care? Get quick care after a fall with deformity or weakness. A hot, red, swollen joint with fever needs same-day care. Chest pressure, sweating, nausea, or trouble breathing can be an emergency. Numbness reaching your hand also needs an exam. These aren't signs of a routine flare. ## What does regenerative shoulder treatment mean for me? PRP is one part of your blood separated by spinning. That process gathers more platelets, which are tiny blood parts. The clinic uses this portion in care meant to support repair. QC Kinetix discusses regenerative options after examining your shoulder. These treatments don't prove that cartilage grew back. ## What happens during a shoulder consultation? Clinic staff ask how your soreness started. You'll show which movements hurt. The exam checks motion and strength. Take prior scans and notes listing your medicines. You can then discuss likely causes and choices. ## Where is the nearest clinic for Gilbert residents? The closest location is 1100 S. Dobson Rd., Suite 210, Chandler, AZ 85286. It sits west of Gilbert. Your route may use Ray, Warner, Elliot, Guadalupe, or Loop 202. The clinic number is (602) 837-PAIN. Check traffic before you leave. ## What is your next shoulder step? At the Chandler office, QC Kinetix offers regenerative care, meaning treatments prepared from part of your blood and intended to support repair. Clinic staff can examine your shoulder and discuss choices. They may find that different care fits better. Bring prior scans and notes listing your medicines. Note which movements make the soreness worse. You'll leave knowing which choices fit the exam. Book a free consultation: --- Plain help for soreness and easier movement.
