Here i go again with my blood pressure! This week low!!! 115 over 65 blood pressure reading, is this a good reading or bad to low? Mine consistently runs 105-115 over 60-65 the last only few days and i still feel ok. I own and tested my BP at my home, its a Omron, I think that is the name. It's a home blood pressure monitor which seems is gives the right readings. Being this low, would indicate low thyroid output?
