Unstable Blood pressure?

I'm 27yr old female. No history of heart disease, I run 2x a week, healthy weight. I went to the dentist to get my wisdom teeth removed. I was ready to go, the dentist gave me nitrix gas, they put the cuff heart monitor on, and all the sudden the dentist just stopped the procedure because my blood pressure wouldnt normalize. My blood pressure was low AND high at the same time. (I have always been told that I have very healthy blood pressure. Im in good shape.) The dentist told me he would consider having my teeth pulled later but in an actual hospital and he would be my 'surgeon'. As a second opinion, I have made an appointment with my primary care doctor to get testing done to why my cuff reading wasnt normalizing. My appointment is in june. Meanwhile, What is wrong with me? Im very freaked out! I'm really upset. Do other people have unstable blood pressure? is it common, or is it just me? I hope I dont have a medical condition.

it could probably be the effect of the nitrix gas causing your bp to fluctuate.
