yes very true, the only way that you can usually tell by looking, is the skin tone. When someone has very low blood pressure they tend to go pale in colour.
Don't forget that low blood pressure can also give you the same symptoms, if you pressure is under 90/60 you can experience the symptoms you describe as well.
I didn't even think of that??
I will have the school nurse check it tomorrow.
Thanks
What is your blood pressure like? If mine gets high I get the fuzzy hearing and dizziness you speak of.
