Disease-modifying therapies (DMT) can help manage multiple sclerosis symptoms. Rehabilitation through physical therapy can enhance muscle strength and control, especially after neurological events. Physical therapy can also improve overall mobility and coordination.
Peripheral Neuropathy
Peripheral neuropathy is damage to one or more nerves in the peripheral nervous system. It can be caused by diseases, infections, drugs, and conditions like radiculopathy. This condition affects the peripheral nerves, leading to symptoms such as numbness, tingling, and pain.
Effective management of peripheral neuropathy requires proper diagnosis and treatment.
Radiculopathy
Radiculopathy is defined as compression of a spinal nerve root. It often results from the compression of spinal nerve roots, leading to symptoms in the arms. One common cause of radiculopathy is pinched nerves in the neck, which can lead to numbness and pain on one side of the body.
Pain relief is the main focus of treatment, with surgical interventions as a possible option.
Additional Symptoms to Watch For
Numbness in the left side of the face can signal a serious condition like stroke or multiple sclerosis. Symptoms that may accompany left side numbness include weakness, dizziness, and difficulty speaking. Nerve problems can also result in tingling, burning sensations, muscle weakness, or oversensitivity.
Recognizing these additional symptoms and seeking prompt medical evaluation is vital.
Vision Problems
Sudden vision disturbances alongside left side numbness can signal potential strokes or multiple sclerosis and require urgent medical attention. These symptoms may point to serious health conditions such as strokes or multiple sclerosis.
Experiencing the following symptoms necessitates immediate emergency medical care evaluation to seek medical attention immediately and avoid serious complications.
Muscle Weakness
Muscle weakness on the left side can accompany numbness and may signal neurological disorders or spinal trauma. Stroke is a leading cause of sudden left side numbness and could also lead to muscle weakness, emphasizing the need for immediate medical attention. Multiple sclerosis, an autoimmune disease, can cause nerve damage that leads to left side numbness and muscle weakness.
Radiculopathy involves compression of spinal nerve roots, potentially causing numbness and muscle weakness on one side of the body. Physical therapy can help improve muscle control and strength, especially after a stroke or spinal injury. Immediate medical attention is warranted for sudden onset of left side numbness, especially if accompanied by other symptoms.
Slurred Speech
Slurred speech combined with left side numbness is a common symptom of a stroke. Sudden onset of left side numbness and slurred speech requires immediate medical attention.
