When someone experiences weakness in their hands and feet, it can be concerning and may indicate a variety of underlying medical conditions. Your uncle's symptoms of weakness in his fingers and toes could stem from several potential causes, and it's essential to approach this issue thoughtfully.

Firstly, weakness in the extremities can be attributed to neurological issues. Conditions such as peripheral neuropathy, which can result from diabetes, vitamin deficiencies, or exposure to toxins, may lead to weakness, numbness, or tingling sensations in the hands and feet. Another possibility is a condition affecting the spinal cord or nerves, such as multiple sclerosis or amyotrophic lateral sclerosis (ALS), which can cause progressive weakness and muscle atrophy.

Musculoskeletal issues could also be at play. Conditions like arthritis can lead to joint pain and weakness in the hands and feet. Tendon injuries or conditions like carpal tunnel syndrome can cause weakness in the hands, particularly affecting grip strength.
In addition, systemic conditions such as myasthenia gravis, an autoimmune disorder that leads to fluctuating muscle weakness, could be a consideration. This condition often affects the muscles that control eye and eyelid movement, facial expression, and swallowing, but it can also impact limb strength.

Given the range of potential causes, it is crucial for your uncle to see a specialist for a thorough evaluation. The best starting point would be to consult a neurologist, as they specialize in conditions affecting the nervous system. The neurologist will likely conduct a comprehensive neurological examination, which may include tests to assess muscle strength, reflexes, and sensory function. They might also order additional tests such as blood tests, electromyography (EMG), or nerve conduction studies to better understand the underlying cause of the weakness.

If the neurologist suspects a musculoskeletal issue, they may refer your uncle to an orthopedic specialist or a rheumatologist, particularly if there are signs of inflammatory or autoimmune conditions.
In summary, weakness in the hands and feet can arise from various medical issues, and it is essential to seek professional help to determine the cause. A neurologist would be the most appropriate specialist to start with, as they can provide a comprehensive evaluation and guide further testing or referrals as necessary. Early diagnosis and intervention can significantly improve outcomes, so it is advisable not to delay seeking medical attention.
