My normal BP is 90/60-100/70. However, I've been at around 150/90 for three days in a row. It all started from a root canal retreatment that my dentist insisted me to sit through after I almost pass out on his chair when receiving anaesthesia shot. I've been feeling heart palpitation (pulse ~115/min), headache, dizziness, weakness, and occassional fainting spells since then. Also, I was on Medrol 24mg/day for the past 4 days. Not sure if it contributes to this. Overall, I'm feeling very crappy. My doctor says that I need to get the dental problem solved first and my BP/pulse will be back to normal. I've been in many illness before and through many stressful situations, never had any issue w/ blood pressure. Does anyone have similar experience? How long does it typically take to be back to normal? How do you deal w/ the headaches and shaky feelings that come with it?
