Update after doctor's appt.
My plummeting blood pressure during/following walking my dog has been as low as 63/43 but currently averaging mid-70's over mid-50's. She says it "could" be because my high cholesterol may cause plaque in arteries, preventing a natural squeezing of them during exercise to allow more blood to the brain, resulting in light-headedness. It returns to low normal with time.

With a paradoxical reaction to pharmaceuticals, I refuse to take Lipitor. (I took it for a year in the past, and it lowered my normally high, good cholesterol and not the HDL, and I had lousy side effects.) I'm back on low-dose asprin and red yeast rice. I lowered it from 401 to 294 in two months with diet change and natural supplements. Being on a keto, no grain diet for two years felt good but sure raised my cholesterol! Has anyone else experienced this?

We're checking for a urinary tract infection, as infections can lower bp. (Did not know that! Seems it would raise it.)

And, I'm scared but am willing to try fludrocortisone to lower bp, but if this will help with "exercise induced low blood pressure" and create other problems for me when I'm NOT walking my golden retriever, I don't know. It would be nice to once more hike in the mountains and deserts of southwest Colorado and not be afraid of passing out!

Any suggestions or experience with this drug would be greatly appreciated.
