常見錯誤

❌The doctor said I have a spinalis injury.
✅The doctor said I have a spinal injury.
💡'spinalis' is a specific muscle name, not a general adjective meaning 'related to the spine' (use 'spinal' for that).
❌I pulled my spinalis while gardening.
✅I pulled a back muscle while gardening.
💡in non-medical speech, 'spinalis' sounds overly technical; use 'back muscle' instead.
