Feeling numbness in the right hand may or may not be hypertension, and hypertension can cause numbness in the hand. Hypertension is a particularly dangerous disease, manifested in the early stage without any symptoms, even 5-10 years the patient does not feel anything, no pain or pain. However, hypertension is a chronic killer, and when hand numbness or slight dizziness occurs early on, it is already a very critical condition and requires early medical attention to control hypertension. Hypertension is now diagnosed by sitting still for 10 minutes in a quiet state, without medication, and having a blood pressure monitor greater than 140/90mmHg, i.e. systolic blood pressure greater than 140mmHg and diastolic blood pressure greater than 90mmHg. However, since there is an error when the patient measures the blood pressure at home, it is recommended that if the blood pressure exceeds 130/80 mmHg when measured in a quiet state, and if the value occurs repeatedly, the patient should seek professional help to control the hypertension as soon as possible.
