Inflammation or degeneration of a tendon or its surrounding sheath.
Because the rating turns on limitation of motion, the most useful evidence is documentation of how much movement you have lost in the affected area. Range-of-motion measurements recorded during a VA examination or by your treating provider are central. These readings show the degrees of motion available and how they compare to normal. Records of pain on motion, tenderness, swelling, or stiffness from clinical visits also help show the severity of the condition. Imaging such as ultrasound or MRI may support the diagnosis and reflect the extent of tendon involvement. Statements from you or people who know you that describe how reduced motion affects your ability to work, lift, reach, walk, or carry out daily tasks connect the clinical findings to real-world impact. Consistent treatment records over time help show that the limitation is ongoing.
