Answer:
Both sides, option B
Step-by-step explanation:
The term bilateral can be broken into two components: root phrase "bi-," root phrase "lateral."
The root phrase "bi-" refers to two, or in many cases both.
The root phrase "lateral" refers to the patient's sides.
Because of this, the term bilateral refers to both sides, so if the patient experiencing bilateral pain, they are experiencing it on both sides of their body.
