My blood pressure is in normal ranges, I just have a fast heart rate, but it's significant, with spikes as high as 170-180. It's not that I won't take the meds, but I'm just curious if they're likely to work in this scenario. The cardiologist thought that CRPS made sense to be the cause but he has no experience with it. I'm not sure what my CRPS doc will say, or if I might need to see a new doctor. I've been overwhelmed with doctors and tests the past 6 months.
