Exercise addiction is a state characterized by a compulsive engagement in any form of physical exercise, despite negative consequences.
 While regular exercise is generally a healthy activity, exercise addiction generally involves performing excessive amounts of exercise to the detriment of physical health, spending too much time exercising to the detriment of personal and professional life, and exercising regardless of physical injury.
 It may also involve a state of dependence upon regular exercise which involves the occurrence of severe withdrawal symptoms when the individual is unable to exercise.
 Differentiating between addictive and healthy exercise behaviors is difficult but there are key factors in determining which category a person may fall into.
 Exercise addiction shows a high comorbidity with eating disorders.
In English law, a nervous shock is a psychiatric illness or injury inflicted upon a person by intentional or negligent actions or omissions of another.
 Often it is a psychiatric disorder triggered by witnessing an accident, for example an injury caused to one's parents or spouse.
 Although the term "nervous shock" has been described as "inaccurate" and "misleading", it continues to be applied as a useful abbreviation for a complex concept.
 The possibility of recovering damages for nervous shock, particularly caused by negligence, is strongly limited in English law.
Road rash is a colloquial term for skin injury caused by abrasion with road surfaces, usually as a consequence of cycling and motorcycling accidents.
 The term may be applied to both a fresh injury and the scar tissue left by an old one.
 The term is sometimes applied to longboarding, skateboarding, and roller skating abrasion accidents, especially those caused at high speeds (as in longboarding).
 Symptoms may include pain and heavy bleeding.
Hypothalamic disease is a disorder presenting primarily in the hypothalamus, which may be caused by damage resulting from malnutrition, including anorexia and bulimia eating disorders, genetic disorders, radiation, surgery, head trauma, lesion, tumour or other physical injury to the hypothalamus.
 The hypothalamus is the control center for several endocrine functions.
 Endocrine systems controlled by the hypothalamus are regulated by anti-diuretic hormone (ADH), corticotropin-releasing hormone, gonadotropin-releasing hormone, growth hormone-releasing hormone, oxytocin, all of which are secreted by the hypothalamus.
 Damage to the hypothalamus may impact any of these hormones and the related endocrine systems.
 Many of these hypothalamic hormones act on the pituitary gland.
 Hypothalamic disease therefore affects the functioning of the pituitary and the target organs controlled by the pituitary, including the adrenal glands, ovaries and testes, and the thyroid gland.

A grease gun injury or injection injury is an injury caused by high-pressure injection of oil, grease, solvents, water, or even air, into the body.
 The most common causes are accidents with grease guns, paint sprayers, and pressure washers, but pinhole leaks in pressurized hydraulic lines occasionally cause this injury.
 Additionally, there is at least one known case of deliberate self-injection with a grease gun.

A chest injury is any form of physical injury to the chest including the ribs, heart and lungs.
 Chest injuries account for 25% of all deaths from traumatic injury.
 Typically chest injuries are caused by blunt mechanisms such as motor vehicle collisions or penetrating mechanisms such as stabbings.
An adverse drug reaction (ADR) is an injury caused by taking a medication.
 ADRs may occur following a single dose or prolonged administration of a drug or result from the combination of two or more drugs.
 The meaning of this expression differs from the meaning of "side effect", as this last expression might also imply that the effects can be beneficial.
 The study of ADRs is the concern of the field known as "pharmacovigilance".
 An adverse drug event (ADE) refers to any injury occurring at the time a drug is used, whether or not it is identified as a cause of the injury.
 An ADR is a special type of ADE in which a causative relationship can be shown.
