I have been on an ace inhibitor for 5 years, and my RSD started a little over one year ago, although I wasn't diagnosed until a few months ago. I read that a few studies have shown that ace inhibitors increase risk of RSD. Should I talk to my primary about it? The problem is that I have "treatment resistant" hypertension, and am also already on a diuretic and calcium channel blocker. I was on a beta blocker, but went off it recently - my primary thinks my blood pressure went down when my pain level decreased after three sympathetic blocks (yeah). So going off the ace inhibitor will mean either increase blood pressure (and headaches that causes me) or trying a less commonly used antihypertensive.

What I read said ace inhibitors increase risk of developing RSD. That doesn't necessarily mean they play a role in ongoing disease.

As anyone else been taken off their ace inhibitor because of RSD?
