Monitor your blood pressure.
I am Dr.Rovena.I had gone through your query and understand your concern.
The normal range for blood pressure is 120/80 mmHg and your number 180/94 mmHg is considered vary high.
Even you don't have a high blood pressure
history It can be the beginning of Hypertension
If it was the first time that your blood pressure is over the normal range it also can be sporadic happening but this we will know only in next days,weeks if your BP is going to stay high.
are common symptoms of high blood pressure.
Untreated high blood pressure can cause serious damage to your heart and brain.
If your blood pressure is still that high and doesn't show any tendency to lower
I suggest you to go to hospital to get the right treatment.
Otherwise If your BP will low in normal value I suggest to monitor it the next 10 days twice a doy and keep note of them.
Hope I was able to help you.If you have further questions feel free to write me.
I will be happy to answer.
