Everyone at least once in their life came across such an unpleasant symptom as weakness in the body without fever. This malaise can occur as a result of illness, or as a result of overstrain. Treatment of the pathology is determined by those factors that provoked it. The reason why muscle weakness occurs and how to deal with such a condition is described in the article.
Characteristics of malaise
Body aches are a common symptom, and many, noticing it at home, measure the temperature.
They believe they have contracted a viral infection. Indeed, these diseases are usually acute and accompanied by fever. However, it happens that there is no temperature, and weakness in the body does not pass. However, a clear localization of discomfort cannot be indicated. It spreads throughout the musculature. Pain in the limbs, back and joints is sometimes so pronounced that it does not allow a person to get out of bed. This pathology arises as a result of the influence of many factors.
For example, it is known that often an individual develops weakness in the body for reasons related to his lifestyle (poor diet, constant overwork, lack of proper rest). Often this condition is encountered by patients with diseases of the musculoskeletal tissue and joints, as well as other organs (liver, lungs, stomach or intestines). In some cases, a feeling of overwork is associated with the onset of a viral infection, which is not accompanied by a fever. Another factor provoking this phenomenon is considered overstrain (mental, physical or emotional).
Causes of the symptom
A feeling of muscle pain and weakness in a body without fever can be caused by many different ailments. The most common are the following:
- Intoxication with spoiled products, botulinum stick.
- Autoimmune pathologies (SLE, joint inflammation, thyroid disease).
- Cancer of the blood and lymphatic system.
- Disorders of the myocardium, blood vessels.
- Neoplasms of various organs.
- Weakened immunity (due to emotional overload, HIV, poisoning).
- Viral pathologies (ARVI, various types of hepatitis, chickenpox and so on).
- Diseases characterized by an acute inflammatory process in the respiratory system or urinary system.
- Mechanical damage to the spine or limbs.
- Arthropod bites (e.g. ticks).
- Diabetes.
- Inflammatory processes in bone tissue or muscles.
- Eating Disorders.
If the ailment does not go away for a long time, a person should consult a general practitioner, a specialist in diseases of the joints, hematopoietic organs or the reproductive system.
The characteristic signs of ailments
One of the reactions to the negative effects of the environment is weakness in the body. The reasons that provoke it can be very diverse, as are the manifestations. Depending on what caused the feeling of being broken, it is accompanied by certain symptoms. For example, increased fatigue is associated with aching muscles and joints, a feeling of drowsiness, pain in the head, loss of appetite, and nervousness. Infections of the respiratory system occur with nasal congestion, discomfort in the joints, cough.

If a personโs immune system is impaired, he feels constant weakness, pressure drops, reduced ability to work. In case of poisoning, not only fatigue is observed, but also nausea, pain in the lower part of the peritoneum, dizziness, excessive sweating, vomiting and diarrhea. Arthropod bites are accompanied by the appearance of small reddish rashes on the surface of the body, aching in the neck, itching. All the ailments described above in the first stages of their development do not cause a temperature increase. However, if you do not attach importance to weakness in the body and other signs of discomfort, the disease can progress and lead to serious complications.
Early symptoms of pathologies
In order to recognize the disease in time and begin treatment, you should pay attention to its initial manifestations. Weakness in the body, which greatly worsens the patientโs well-being, is often associated with other signs of malaise. As early symptoms, experts call:

Pregnancy is considered one of the happiest periods for any woman. However, these months may be accompanied by rather unpleasant symptoms. Great weakness in the body is one of the first signs of the birth of a new life. Such a malaise can be caused by various reasons. Among the factors that provoke a feeling of weakness in expectant mothers, the following can be listed:
- Increased production of a substance that promotes muscle relaxation. In this case, the woman feels pain in the region of the lower back and back.
- Lack of vitamin D, as well as insufficient intake of calcium-containing foods. During the gestation, the female body experiences an increased need for substances necessary for the normal course of pregnancy and the formation of the embryo. If the diet of the expectant mother is not diverse, she may experience weakness and aches.
- Softening the pubic joint. It is also associated with a lack of calcium in a woman's body. With the development of this condition, the expectant mother suffers from pronounced pain in the joints.

Excessive fatigue
Sometimes, against the background of emotional, mental or physical overload, a person feels unwell. Feeling when the whole body hurts, and weakness can be explained by a lack of sleep and rest. All this is accompanied by a significant decrease in memory and attention, as well as numbness of the limbs. Sometimes such a malaise is associated with disorders of the nervous system.

If the disease affects the respiratory system, a person develops a cough, discomfort in the throat. Weakness in combination with nausea and vomiting can be a sign of various ailments (cirrhosis, gastritis, poisoning with spoiled foods, bowel obstruction, stomach pathologies). Such symptoms can provoke prolonged exposure to the sun or heat stroke.
Pathology of the myocardium and blood vessels
In cases of impaired heart activity, a feeling of brokenness is accompanied by other signs of deterioration of well-being. For example, weakness and trembling in the body, which are accompanied by a cut in the chest, in the region of the shoulder and shoulder blade, indicate the development of a heart attack. Cerebral hemorrhage is associated with nausea, lethargy, numbness of the muscles and visual pathologies. In case of rhythm malfunctions, an increase in the heart rate and the appearance of fatigue are possible. The feeling of cold combined with weakness and a feeling of squeezing the sternum is a consequence of coronary heart disease.
There are many myocardial pathologies that are similar to each other in their symptoms. Only a specialist can make a correct diagnosis based on the results of diagnostic procedures.
