Use your own words.
You do not need the exact medical term. Explain what you have noticed and what you would like to understand. That is more useful than choosing a diagnosis in advance.
Ask about the aim.
What is the proposed step intended to achieve? How does it connect with the rest of your care? Ask for an explanation when a term or sequence is unclear.
Discuss options and limitations.
Are there other approaches? What are the limitations? What is needed before making a decision? These questions help you understand the plan without reducing the choice to time or cost alone.
Clarify the next contact.
What follows the visit? When and how can you ask further questions? Note the details that matter to you and confirm them with the team.
