Translation guide
In Japanese, referring to an 'affected part' of the body depends on context: medical, casual, or specific body areas. The most common and versatile term is 患部 (かんぶ), used in medical or treatment contexts. For general reference to a painful or problematic area, 痛むところ (いたむところ) or 悪いところ (わるいところ) are natural. In everyday conversation, simply naming the body part is often sufficient.
Referring to the specific part of the body that is injured, diseased, or receiving treatment.
Please keep the affected area clean.
Apply this medicine to the affected part.
Means 'around the affected area'. Used in medical contexts to describe the surrounding region.

Casually referring to a part of the body that hurts or has a problem, without strict medical terminology.
Literally 'the place that hurts'. Very natural in everyday conversation when pointing out a painful spot.

Literally 'the bad place'. A common, slightly vague way to refer to an injured or problematic body part.

患部 is a formal medical term used by professionals or in written instructions. 痛むところ is a casual, everyday expression. Use 患部 when talking to a doctor or reading medical labels; use 痛むところ when speaking casually about your own pain.
