Myalgia describes pain in one muscle or a specific group of muscles and is a common symptom after strenuous physical activity or muscle trauma.

The most common causes of muscle pain are sports activity that is not practiced correctly. When you make a physical effort, any movement may need to activate a different group of muscles, and any wrong movement leads to injury and temporary damage to one muscle or group of muscles.

The muscle may need 48 hours to heal after being injured by strenuous physical activity, with the need to take a sufficient amount of rest.

Polymyalgia rheumatica is an inflammatory disorder that causes muscle pain and stiffness, especially in the shoulders and hips. Signs and symptoms of polymyalgia rheumatica usually begin quickly and are worse during the day.

Most people develop polymyalgia rheumatica after age 65. It rarely affects people under 50 years of age.

This condition is associated with another type of inflammation known as giant cell arteritis. Giant cell arteritis sometimes causes headaches, difficulty seeing, and pain in the jaw and scalp. Both conditions may appear together.

Symptoms
Signs and symptoms of polymyalgia rheumatica occur on both sides of the body and may include:

Feeling of soreness or pain in the shoulders
Soreness or pain in the neck, upper arms, buttocks, hips or thighs
Stiffness in the affected areas, especially in the morning or after a long period of rest
Limited range of motion in affected areas
Pain or stiffness in the wrists, elbows, or knees
More general signs and symptoms may occur, including:

mild fever
fatigue
A general feeling that you are not feeling well (malaise)
Anorexia
Unintentional weight loss
Depression
When do you visit the doctor?

It’s something new
hinder your sleep
Limits your ability to do your usual activities, such as getting dressed.

the reasons
The exact cause of polymyalgia rheumatica is unknown. There seem to be two factors behind the development of this condition:

Genetic genes. Certain genes and genetic changes may increase the risk of infection.
Exposure to an environmental stimulus. New cases of polymyalgia rheumatica tend to go into cycles and may develop seasonally. This suggests that an environmental trigger, such as a virus, may have a role. But the specific virus that causes polymyalgia rheumatica has not been identified.
Giant cell arteritis
Polymyalgia rheumatica and another disease known as giant cell arteritis share many features. Many people with this disease also have symptoms of another disease.

Giant cell arteritis results in inflammation of the ends of the arteries, most often of the skeletal arteries. Signs and symptoms include headache, jaw pain, vision problems, and looseness of the skull. This condition may lead to stroke or blindness, if left untreated.

risk factors
Risk factors for polymyalgia rheumatica include:

Age. Polymyalgia rheumatica affects the elderly particularly well. It mostly occurs between the ages of 70 and 80.
sex. Women are more likely to have this disorder two or three times.
Sweat. Polymyalgia rheumatica is more common among white people with ancestors from Scandinavia and northern Europe.
Complications
Symptoms of polymyalgia rheumatica can severely affect your ability to perform daily activities, such as:

Getting out of bed, standing up after sitting in a chair, or getting out of the car
