# Know when shoulder soreness can wait and when it needs care *Who Should Consider Care — Shoulder Regeneration Glendale* > Shoulder regeneration Glendale guidance on lasting soreness, warning signs, when to book a visit, and what to take to an exam. ## Get sudden weakness checked quickly After a fall, the shoulder may hurt and the arm may suddenly become weak. That isn't the same as a dull ache that grew over several months. New weakness needs a prompt exam, especially when you can't raise the arm. Gradual soreness usually gives you time to change activity and arrange regular care. Even so, an ache that keeps waking you or blocks basic tasks deserves attention. You needn't wait until the arm becomes useless. ## Go now when warning signs appear Get urgent help for chest pressure, sweating, nausea, or shortness of breath. Shoulder soreness can sometimes come from the heart instead of the joint. Fever with a very warm, swollen shoulder also needs quick care. Prompt care matters after a hard fall if the shoulder looks misshapen or won't move. Growing numbness or weakness can begin in the neck or nerves. An ordinary scheduled shoulder appointment mustn't delay care for these symptoms. ## Book a regular visit when soreness stays Book a regular visit if sleeping, dressing, or reaching remains difficult. A clinician can check movement and strength, then compare the findings with how the ache began. An X-ray may help when the joint feels worn. The visit may lead to activity changes, focused exercise, medicine, or a talk about procedures. Ask which choice has the best support for the shoulder problem found. The answer needs honest limits and a date for another check. ## Take details that make the exam useful Take your current medicines and any older shoulder reports. Note whether the ache started slowly or followed a fall. If you've tried exercise or therapy, record what helped and what made it worse. Show the clinician the movement that stops you. Say whether you most want better sleep, dressing, lifting, or work. Specific details tell the clinician more than a general soreness score. ## Sources 1. 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. 2. 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%).

FDA states verbatim that stem cell, stromal vascular fraction, umbilical cord blood, Wharton's jelly, amniotic fluid and exosome products 'have [not] been approved for the treatment of any orthopedic condition, such as osteoarthritis, tendonitis, disc disease, tennis elbow, back pain, hip pain, knee pain, neck pain, or shoulder pain.' The only FDA-approved stem cell products in the United States are blood-forming (hematopoietic progenitor) cells from umbilical cord blood, approved only for disorders of blood production, and there are currently NO FDA-approved exosome products.

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.

A 2026 meta-analysis of 10 randomized trials (n=591) found PRP and corticosteroid indistinguishable at 3-6 weeks and 3 months, with PRP pulling ahead at 6 months: ASES +10.8 (95% CI 4.71-16.80), Constant-Murley +10.7 (1.21-20.27) and VAS pain -0.8 (-1.45 to -0.18), plus fewer adverse events (RR 0.66, 0.44-0.99). The authors describe the benefit as statistically significant but CLINICALLY MODEST.

DOI: 10.1002/ksa.70416. 6. A meta-analysis of nine randomized trials (469 patients) found corticosteroid superior to PRP in the SHORT term on Constant, Simple Shoulder Test and ASES scores, no difference at mid-term, and PRP superior in the LONG term on Simple Shoulder Test and ASES. The authors state explicitly that none of these differences reached the minimal clinically important difference.

List the reaches, lifts, and positions in bed that make it worse, and take your current medicines and older X-rays to the appointment, so the clinician can compare your history with movement and strength during the exam.
