The aromatase inhibitors can cause some changes in epithelial tissue so maybe that affects high blood pressure? I kind of think that just having cancer, and treating it, is such a big life change that it gets hard to separate out what is causing what under already stressful circumstances. I had a reaction, twice, to anastrozole of a kind of low 'burning' in my mouth, as if I'd eaten hot chiles or very spicy food. It went away both times I discontinued anastrozole after trying it. [I quit anastrozole over a different side effect. But never found anyone else who had that reaction to the med.]

The odds are that your doctor knows who are other great doctors and hopefully can match you up with another winner since it can make all the difference as we know!
