<s>[INST] I am a 43 yr old female, I exercise regularly, I don t smoke and I never have, I don t eat a lot of salt. I am about 15lbs overweight. I am not on any medications, but, my blood pressure has been ranging from 138-143 top number and 98-109 bottom number since yesterday. ( or maybe longer I havent been checking it) My only symptom is my face flushing. I have felt some numbness in my thumb on my left hand, but I dont think it s related? Everyone says my bottom number being so high is dangerous, and I should go to the ER, but I feel fine. Please advise. Thank you! [/INST] Hello, I can understand your concern. Even though your systolic blood pressure (upper number) is high too, it can be considered normal due to your age being 43 years. Your diastolic blood pressure (lower number) is surely high as your friends are pointing out, and it needs to be corrected. Normally it should be 80 mm Hg while your is about 100 mm Hg. The facial flushing and thumb numbness might be due to higher blood pressure, too. I advise you to visit your physician or cardiologist for physical examination and needful treatment to lower the blood pressure. I hope this information helps you. Thank you for choosing Chat Doctor. Take care. Best, </s>
