Introduction
Lack of muscle strength despite having muscles is generally caused by conditions such as viral encephalitis, polymyositis, and myasthenia gravis, and can be treated with medications or surgery. Viral encephalitis can cause nerve damage, leading to muscle weakness. In addition, muscle weakness may also result from Guillain-Barré syndrome. It is advisable to go to the hospital for relevant tests and choose appropriate treatment accordingly.
Muscle weakness despite having muscle mass is generally caused by conditions such as viral encephalitis, polymyositis, and myasthenia gravis, and can be treated with medications or surgical interventions.
1. Viral Encephalitis
Viral encephalitis can cause nerve damage, which may lead to muscle weakness and functional impairment. Under a doctor's guidance, neurotrophic medications such as mecobalamin tablets or vitamin B complex tablets may be used to alleviate symptoms.
2. Polymyositis
Inflammation of the muscles, such as in polymyositis, may result in weakened muscle contraction, causing fatigue, numbness, or pain. Treatment typically involves non-steroidal anti-inflammatory drugs (NSAIDs), such as aceclofenac tablets or diclofenac tablets, selected under medical supervision.
3. Myasthenia Gravis
Myasthenia gravis is a common neuromuscular junction disorder that causes muscle weakness and impaired signal transmission after onset. In severe cases, thymectomy surgery may be recommended under medical guidance.
Besides the above, muscle weakness could also be caused by Guillain-Barré syndrome. It is advisable to go to the hospital for appropriate diagnostic tests and receive targeted treatment accordingly.
