<s>[INST] Hi. For the last month I've been experiencing strange aching feelings in my arms and chest, I get palpitations but my pulse rate is slow:about 60 bpm and my blood preasure shoots up to about 170/92, then my BP drops back to mormal.  This happens two or three times a day. I am a fit 58 year old woman; weigh 110 lbs, and 160cm in height.  Thanks [/INST] 170 sometimes and sometimes normal ...these things are due to adrenergic surges ..you need drug as beta blocker as metoprolol bidoprolol atenolol..but please see your local doctor he will decide which is better drug for you ...avoid coffee tea fast foods fried foods ...donot overexert yourself physically ...also get your sugar checked ..you can go for slow morning walk and avoid exposure to cold ... </s>
