The root "dynia" means?

• A. Pain
• B. With pain or difficulty
• C. Swelling
• D. Running

Answer: (A)

In medical terminology, dynia denotes pain in a specific area. It’s used as a suffix to indicate that the patient is experiencing pain there, often forming terms like gastrodynia (stomach pain) or cephalodynia (head pain). So the root dynia literally means pain. It’s not about swelling (edema) or running, and it isn’t a cue for “with pain or difficulty” in itself—those ideas come from different word parts.
