Your blood pressure is 98 over 63 - is this okay?

Yes, it's just fine, great even. Below 120 over 80 is a good target. Between 90 and 120 is normal for systolic and between 60 and 80 is normal for diastolic. Low blood pressure is not a problem provided that you do not have OTHER issues. Do you feel "light headed", feel like you're about to pass out or just don't have any energy? Have you been checked out lately by a doctor? If your low BP is due to low thyroid or other problems you might want to address those issues. However, if everything else is relatively normal and you just have those low numbers routinely... that's fantastic. As long as you don't feel any bad side effects and your doctor says you're ok, be delighted with those numbers.
