tl;dr: After an orthopedist diagnosed a Grade III partial-thickness subscapularis tendon tear and began aggressive treatment (including shockwave therapy and a homeopathic injection), the author ran their DICOM MRI files through Claude Code (Opus) for a second opinion, which instead found an intact tendon with only mild tendinosis. A follow-up arbitration run by Claude sided with the "no tear" reading at moderate-to-high confidence. The author acknowledges they can't fully trust either verdict but is now skeptical of the clinic's intervention-heavy plan.
