Why is My Arm Sore and Shaking?

There are a number of possible causes for arm soreness and shaking. It is important to identify the underlying cause in order to determine the best course of treatment.

Muscle Fatigue

One of the most common causes of arm soreness and shaking is muscle fatigue. This can occur when the muscles have been overworked or strained, resulting in pain and trembling. Muscle fatigue can be caused by repetitive motions, such as typing on a computer or playing a musical instrument, or by lifting heavy objects. Resting the affected area and avoiding activities that may aggravate the condition can help reduce symptoms.

Nerve Damage

Nerve damage can also cause arm soreness and shaking. This type of damage can be caused by an injury, such as a fracture or sprain, or by certain medical conditions, such as diabetes or multiple sclerosis. Treatment for nerve damage typically involves medications to reduce inflammation and pain, physical therapy to strengthen the muscles, and lifestyle changes to reduce stress on the affected area.


Anxiety can also cause arm soreness and shaking. Anxiety-related tremors are usually accompanied by other symptoms, such as sweating, rapid heartbeat, and difficulty breathing. Treatment for anxiety-related tremors typically involves relaxation techniques, cognitive behavioral therapy, and medications to reduce anxiety.
