Sometimes pain and: anxiety can elevate your blood pressure. Other times you discover you actually have hypertension and need treatment. It would be worth your while to purchase a blood pressure cuff and record your pressures at home and show them to your health care provider so you can receive treatment if necessary. This could avoid long term complications of untreated hypertension if it is present.

Recheck BP: That your BP was on the high side is not unreasonable given that u may be in pain from esophagitis. Many things affect BP,including pain, incorrect cuff size, anxiety, etc. Therefore one should never panic by 1 reading, but rather u ought to monitor your BP. If it is consistently > 120/80, then for starters you ought to make lifestyle changes, including but not limited to low salt diet.
