Testosterone, estrogen, etc...can cause fluid retention in the extremities such as the feet and ankles. My thought would be that if your BP is high, then see a doctor because there would be a better possibility of congestive heart failure. It isn't a heart attack, but it is a weakening of the heart and it's ability to send enough oxygen and blood to the extremities and these can lead to a heart attack later. If this does concern you then you really should see a doctor. I'm not a doctor but I have done diagnostic work for doctors in pathology as well as offering them the best treatments for patients. Just keep an eye on BP, any irregular heart beats, and use your best judgment.
