I have been monitoring my BP at home and have found my left arm usually 10 - 20 degrees higher than my right...ie last evening 179/100 left  145/97 in the right...last week it showed in my left arm 198/120 with a pulse of 122 (I did speak with my doctor - and was diagnoised with a sinus infection
Hi there, and thank you for your question. I can appreciate that you may have a sinus infection if you complained of symptoms relating to this issue, but I highly doubt that this is what's causing your blood pressure to be so high. I would like to suggest that you physically consult with your doctor as your blood pressure is very high and seems to be persistent seeing that in the period of one week you had such high readings. It would be advisable to have this issue managed as soon as possible as complications such as stroke, cardiac failure and kidney related issues can arise from uncontrolled high blood pressures. It would also be wise to have both arms checked to see if there is a genuine difference between the pressures on both sides. A condition called dissection of the aorta needs to be excluded if there is a difference of greater than 20 %. I hope you can get medical attention soon please and good luck.
