Wasky, 16 days post-op is not very long at all for your body to adjust to the shock it has been through. If you've been taking any steroids, those can raise your bp and pulse, and it can take a few weeks to settle down, or so I was told by the docs.
I developed high bp after CK last March, and I'm still on meds. Initially, they thought it was from the steroids, but it didn't go down. I thought it was because of change in activity level, and slight weight gain, but I've been fairly active and my doc thinks I'm at a healthy weight. Primary care doc says I was just a hypertension case waiting to happen, and CK just pushed me over the edge.
On the other hand, I wrote to Dr. Chang at Stanford, and he said he doesn't think a right-side AN like mine could cause hypertension. However, he told me to look at the work of neurosurgeon Peter Janetta, who has studied the effects of left-sided brain stem compression on hypertension. In fact, if you look in the general AN forum, you'll see someone posted a link just this week about Type II diabetes and compression of the medulla, by Dr. Janetta. This article references his other work. I've had too many other "fish to fry" than to go searching for answers to my bp probs (I've got balance and vision issues, and am going to the vestibular disorders clinic in a couple weeks)
Here's hoping everything levels out for you over the next few weeks. Stay as active as the docs allow, and eat healthy!
