Checking the circulation in my leg is likely to be futile.
I do have circulation problems, but they originate in my heart, not my leg. I have heart failure, that’s a given even if the cause is uncertain. That’s because I have two conditions that can cause heart failure, a calcified and, in consequence, narrowed, aortic valve which, I suspect, is responsible for the persistent cramp in my hands and feet as it can impede blood flow to the extremities. And I also have COPD.
