English for symptoms and injuries centers on describing how the body feels, what has happened, and when to get help. Learners need both everyday words and more clinical words to explain problems clearly in conversation, at a pharmacy, in a clinic, or in an emergency. The language often depends on severity, duration, and the part of the body involved, and it connects closely with Body Parts.

Common symptoms describe how illness affects the body. Fever, cough, nausea, dizziness, fatigue, and rash are high frequency nouns for reporting what a person feels or shows. These words are often used with intensity and duration words to show whether the problem is mild, severe, constant, or recurring.

Pain vocabulary helps describe the quality of discomfort, not just its location. Ache, sharp, throbbing, stabbing, dull, and intermittent are common ways to explain whether pain is steady, cutting, pulsing, or coming and going. These words often appear with body part phrases such as Body Parts and are especially useful for describing Exercise and Movement related strain or injury.

Severity words show how serious a symptom or injury is. Mild, moderate, severe, unbearable, and tolerable are common scale words that help describe pain and illness clearly in everyday speech and in basic medical conversations. These words often work with symptom nouns, such as fever or cough, to show how bad the condition is.

Word or Phrase	Definition	Example

Tolerable	Tolerable means unpleasant but still manageable.	The discomfort is tolerable, and she can wait.

Duration words show how long a symptom has lasted and how often it appears. Constant, occasional, sudden, chronic, and recurring help distinguish a short event from a long term condition and a steady problem from one that returns. These words are central in clinics because they help separate a passing problem from something that needs ongoing care.

Word or Phrase	Definition	Example
Constant	Constant means continuing without stopping.	The pain is constant, and it never fully goes away.
Occasional	Occasional means happening sometimes, but not often.	He has an occasional cough, and it is not very strong.

Injury words describe damage to the body after impact, twisting, or a fall. Cut, bruise, sprain, strain, fracture, and concussion are common medical and everyday terms, and some overlap with casual language, such as bruise and contusion. These words often lead to first aid phrases, a request for help, or a decision to go to the Under the Weather side of the conversation where someone sounds unwell.

Medical language changes with register, from casual everyday speech to more clinical wording. Tummy, bump, and bruise are common informal words, while abdomen and contusion sound more formal and precise.

Clear symptom language helps people explain progress, report changes, and know when the body is getting better.
