I have have had hypotension all my life after I had a kidney infection a few months ago my systolic BP went way up. Is there a direct correlation of having a kidney infection change my systolic measure?

Yes. Anytime you get a fever, your body is working to fight off an infection. Fever raises your temperature, speeds up your heart rate and raises your blood pressure levels. This increased blood pressure is due to "vasoconstriction"– a narrowing of blood vessels. Although the infection has been a few months ago, your body may take months or even longer to adapt.
Kidney infection can cause changes and fluctuations in blood pressure. The infection can cause a drop in blood pressure. If left untreated, kidney infections can lead to potentially serious complications, such as kidney scarring. This can lead to chronic kidney disease, high blood pressure and kidney failure.
