High blood pressure (hypertension) - Symptoms 

Symptoms of high blood pressure 

High blood pressure (hypertension) usually has no obvious symptoms and many people have it without knowing.

Untreated high blood pressure can lead to serious diseases, including stroke, heart disease and kidney failure.

The only way to know if you have high blood pressure is to have your blood pressure measured. All adults should get their blood pressure checked at least once every five years.

In some rare cases, where a person has very high blood pressure, they can experience symptoms, including:

Visit your GP as soon as possible if you find that you have any of these symptoms.

Find out more about who is at risk of high blood pressure.


If you are pregnant, it's important to have your blood pressure checked on a regular basis, even if it isn't high.

Watching your blood pressure while you are pregnant reduces your risk of developing pregnancy-induced hypertension.

This can lead to a serious condition called pre-eclampsia where there is a problem with the placenta (the organ that links the baby’s blood supply to the mother’s).

had ECG done and was told it was normal. Still having palpitations but didnt have one during the few seconds of the ECG test. Becoming more unwell with blood pressure up again higher than before, asthma and chest infection diagnosed by walk in centre and put on steroids and antibiotics. Feeling very unwell and still cant get to see my gp for another 10 days been waiting a week already. Very poor service from GP.

I have been having palpitations and missed heart beats for about 6 weeks, and two weeks ago had severe chest pains but had no one to look after my children so couldnt call an ambulance. The pains still happen now but less severely and only every few days or so.
I went to the GP today to ask for an ECG as directed by a consultant for something else who wanted to change some meds. The GP took my blood pressure (137/ 98) which is higher than it's ever been when its normally 110/70. GP said this was normal.
Should I have had a more thorough response? My ECG is not for another 2 weeks.

JennyMon, If I were you I'd get a second opinion from another doctor. You shouldn't be getting chest pains and especially If you your BP is regular or down to normal. if not, that can be the cause of the chest pain and maybe your medication needs some more adjusting. Why are you getting high BP because knowing that can help enormously. It can be from age, diet, stress, lifestyle or genetics. Do you drink enough water?
At least if you get another dr you can insist they investigate it further. Better to be proactive, then you know what your health is doing. Good Luck

my blood pressure has been very high for the last 6 weeks, and iv had this sharp pain in the left side of my chest for the same amount of time. iv been having my BP checked every week and my medication changed accordingly, but my GP dosent seem to think that the pain im having is related and thinks it muscle and will not send me for any test only a chest xray that iv already had and it was normal what do I do
