Thank you for reaching out regarding your father's symptoms. Hand tremors, especially in a 64-year-old patient with a history of high blood pressure and joint pain, can arise from several underlying conditions. Essential Tremor: This is a common neurological condition that causes involuntary shaking, particularly in the hands, and may worsen with movement or stress. Parkinson's Disease: While tremors are a hallmark symptom, they often present alongside rigidity and slowness of movement. Early diagnosis is crucial for effective management. Medication Side Effects: It's important to review any medications he is currently taking, as some can lead to tremors as a side effect. Metabolic Factors: Conditions like thyroid disorders or electrolyte imbalances can also cause shaking. Psychological Factors: Stress and anxiety can manifest as physical symptoms, including tremors. Given your father's situation, I strongly recommend scheduling a consultation with a neurologist. We  will conduct a thorough evaluation, which may include a neurological examination and, if necessary, imaging studies or lab tests to determine the cause of the tremors. Early diagnosis and treatment are vital, and I encourage you to seek professional help as soon as possible. Regards !! Dr. K.

Shivering of hands at 64 years old can be a sign of essential tremors, Parkinson's disease or a side effect of certain medications. Joint pain and high BP may be coexisting problems, they may not be directly related to the shivering.
