I am a 73 yr old male and have been getting cortisone injections in my back for herniated discs and noticed the same day that my blood pressure went up and my face was red and flushed. I get dizzy when I raise up from sitting position..even though I'm on blood pressure medication my bp was high for several days after having the injection...I'm due to have another injection this week but have decided not to have it because of the bp issues and dizziness..I also have diabetes ll ..
