Fibromyalgia and peripheral neuropathy are two conditions that affect the central nervous system, resulting in pain. Aside from muscle pain, fibromyalgia also involves sleep disturbance, mood changes, and memory issues. It is believed to be caused by a physical trauma or psychological stress, but the exact cause is still unknown. Fibromyalgia is often accompanied by other conditions, such as anxiety, irritable bowel syndrome, and depression.
Peripheral neuropathy refers to damage caused to the peripheral nerves, resulting in weakness and numbness. Peripheral neuropathy commonly occurs in the feet or hands.
