Acute and chronic when used to describe disease is that acute means brief, dangerous, and an extremely severe pain disease while chronic refers to a medical condition that lasts over a long period.
Chronic can be defined as something that recurs, habitual, and always present, while acute refers to a geometrical angle that is less than 90 degrees.
In the medical field, acute always means the onset of disease, while chronic refers to a disease that grows and develops gradually and slowly.
In an acute medical condition, the people might recover quickly, but in chronic conditions, the disease may last for a lifetime and may take a long time to be relieved. Acute pain starts suddenly, which is a result of injury or a certain medical condition, while chronic pain is a slow-growing process of pain developing in certain parts of the body.
When it comes to hospitalization, acute pain may not need it since their cases are reversible, while a chronic patient might be hospitalized, and their cases are not reversible.
