<s>[INST] My blood pressure is 148/98, heart rate is 101 bpm. I have been extremely dizzy for the past three days with lots of back pain and severe headaches. I also am experiencing a lot of star vision. I have been on high blood pressure meds for the past 21 years. I am female and am 44 years. [/INST] Hello and thanks for writing.I can understand your concern and would try to help you in the best possible way. Your problems suggest improper control of blood pressure. Dizziness may be due to transient low BP or medication side effect that you are taking. Whereas headache may indicate elevated BP.Please mention what medications you are taking and in what dose and frequency so that i may be able to get a clear medical history. You would require an ambulatory BP monitoring i.e.. BP monitoring by a wearable device for 24 hours to detect any fluctuations. I suggest you consult a doctor who may help to get your BP under a better control by doing so medication modifications. </s>
