How do you say "It's strong" in Japanese?

Quick use

Use つよいです (tsuyoi desu) at the hospital or clinic when the pain or symptom is strong.

• Learn the whole phrase first.
• It is often used after you already named the symptom.

Practical note

This is more useful after context is already clear, not as your very first line. For example, say the symptom first, then add つよいです.
