I am 28 years old and a mother of three. My youngest is two months old, and during my pregnancy I started to have pain in my lower left side. It turned out to be a kidney stone. My doctor told me that they would pass after I gave birth. Well, I'm still in pain, and now my blood pressure is very high. Could it be pain causing the high blood pressure?
It's true that pain can cause a temporary increase in blood pressure, but over time that effect diminishes; chronic kidney stone pain should not cause your blood pressure to elevate, so something else may be going on. If your pain is still continuing and your physician is unaware of your blood pressure situation be sure to inform her of it.
It is possible that the kidney stone has caused a worsening of kidney function, which could increase blood pressure. Alternatively, if you're taking OTC pain relievers regularly those may raise your blood pressure. All of this is definitely something to talk about with your doctor.
