Your symptoms of anxiety, sudden rises in blood pressure, and shaky hands may be due to stress, panic attacks, or an underlying medical issue such as thyroid or cardiovascular problems. You should monitor your blood pressure carefully and note when these episodes occur. Practising relaxation techniques such as deep breathing, meditation, or gentle exercise may help manage anxiety. Please consult a doctor promptly to rule out serious medical causes and discuss appropriate treatment, which may include therapy, lifestyle changes, or medication.
