My husband recently had a major surgery and since has had blood pressure going way up and several hours way down. Having a real problem getting it under control.

I am 78 years old and my Blood Pressure goes up and down. Last month at my Primary DoctorOffice my BP was 92/67. He asked if I was dizzy or light headed and I am not…At times my BP will go up to 140/80… This has been going on for a couple years now.. doctors are not concerned because I am not dizzy. I had some imaging done recently on my upper spine and it showed a mass on my Thyroid and I have an appointment at Mayo Clinic with an Endocrinologist and wander it this has something to do with my BP going up and down. I just bought a BP machine to check it at home since it went down to 92/67. Many times after I swim in the am and get home I just get very tired, kind of spacey and have to lay down. I feel like my BP is low…and that is why a got BP Sleeve to check at home. I only take Eliquis 5mg twice a day for medication.
