Not sure how low my blood pressure is going but it’s normally about 90/40 so I don’t have much room to play around. I bought an at home monitor but it got so tight taking the reading that I had horrible pain. I have fibromyalgia so I can’t take stuff like that. I just bought a regular cuff on Amazon (already have a stethoscope) so I figured I can watch some You Tube videos and figure out how to take it myself.
