Lack of energy and weakness
The clinical name of this symptom is asthenia. Angina patients may feel a severe lack of energy that impairs their normal functioning and day-to-day chores. The patient may experience weakness in key areas of the body such as the legs or arms. Weakness in some cases may be chronic, continuous or temporary.
This symptom appears due to an accelerated metabolic waste and metabolic stress that results in excess energy expenditure.
Symptoms of weakness may appear slowly over a period of time or immediately. It is sometimes associated with tremors, muscle cramps, and slow movement. Thus, patients with symptoms of angina may not be able to stand for a period of time, especially during acute episodes, and may also have difficulty speaking or swallowing and experience lethargy.
