I took a digital blood pressure cuff with me and took my pressure regularly--still do. At first, I had to stay below 120/60. I secretly started lifting light weights on circuit machines
about 3 months post dissection, mostly just testing the blood pressure, seeing where I could go, what elevated my pressure. At 5 months, with no change in the occlusion (per MRA), I was officially cleared to lift as well as continue to do cardio.
