Mikale is right. The top number is ok. (Systolic) the bottom number (diastolic) is low. Are you on any new meds? Either way, you should get that checked soon. Also, in the meantime, if you can, check your readings randomly during the day. Check Lt. arm, right arm, sitting and standing. Record your readings so your doctor can get a better idea of what's going on. Good luck.

As the systolic pressure rises with age due to the stiffening of the aorta, more blood is forced into surrounding blood vessels during the heart beat, and this then causes less volume of blood remaining during the resting phase to maintain the diastolic blood pressure, which is why it can become significantly lower than the rising systolic. This can develop into diastolic hypotension.
