- Weakness due to chronic inflammatory processes
Causes of Weakness in the Forearms
Weakness in the forearms can arise for a number of reasons, and understanding them is very important for accurate diagnosis and subsequent treatment. One of the main causes is overload of the muscles and tendons, which is often seen in people whose work involves prolonged use of their hands, such as athletes or office workers who spend a lot of time at the computer. This type of weakness can occur due to carpal tunnel syndrome or tendinitis, which requires timely medical attention.
Another cause of weakness in the forearms can be neurological disorders, such as nerve damage or multiple sclerosis. These conditions can lead to loss of strength in the arms and forearms, as well as other accompanying symptoms like numbness or tingling. It is also important to note that some systemic diseases, such as diabetes or hypothyroidism, can affect muscle strength and functionality of the limbs, which also requires professional intervention.
