High blood pressure can cause numbness of the fingers. Patients with high blood pressure can affect the perfusion of brain tissue, resulting in insufficient blood supply to the brain and numbness of the fingers. On the other hand, high blood pressure can also cause insufficient blood supply to the arm, making the nerves of the arm ischemic, and numbness of the fingers can also occur. Numbness of the fingers in patients with hypertension suggests that the patient’s blood pressure is not well controlled, and should be actively carried out to lower the pressure of the treatment. In addition, if patients with hypertension have normal blood pressure, but often have numbness in the fingers, they should pay attention to whether there is the possibility of peripheral neuropathy. Or the patient has a combination of unstable angina pectoris, unstable angina pectoris patients may also appear numbness of the fingers.
