If you have sustained an injury to your radial nerve at the upper arm level on your left arm, you may be experiencing weakness or numbness in your wrist, hand, and fingers. This type of injury can be caused by trauma, such as a fracture, dislocation, or crush injury. It can also be caused by compression, such as when you lean on your arm for an extended period of time.
It is important to seek medical attention if you suspect that you have injured your radial nerve. Your doctor will perform a physical examination and may order imaging tests to determine the extent of the injury.
It is important to follow your doctor's recommendations for treatment and to avoid activities that may exacerbate your symptoms. With proper treatment and care, most people with radial nerve injuries can recover fully and regain normal function in their arm and hand.
If you are experiencing weakness or numbness in your left arm, it is important to seek medical attention right away. Your doctor can help you to determine the cause of your symptoms and develop a treatment plan to help you recover.
