What would cause your blood pressure to flucuate? I can be sitting watching TV or reading and my blood pressure jump from 134/82 to 158/118, and then gradually go back down? I've been on blood pressure medicine for a few years. Last August I was taken to the ER with my right lower leg red, swollen, and very painful. After ruling out a blood clot it was determined I had cellulitus, during that period of 6 weeks that it took for it to go away, my blood pressure was extremely low, 100/58? It gradually went back up to what's normal for me.

IT sounds like you've seen many healthcare professionals about this. Have you asked this question of them? Blood pressure can change for many reasons, and the cause of the change for many more. At this point it would be reckless to suggest anything as this is a question for your doctors.
