Based on your symptoms of hand shaking that worsens with stress and activity, you may have a common condition called Essential Tremor. While I cannot prescribe medication online, the most frequently prescribed first-line treatments are beta-blockers (like Propranolol) or anti-seizure medications (like Primidone). These help reduce the shaking during tasks. Because these drugs affect heart rate and blood pressure, you must consult a doctor or neurologist for a proper diagnosis. They will evaluate your health and safely prescribe the right medication and dosage for you.
