I went into heart failure 10 years ago at the age of 34 and after my hospilization I was dx with venous insufficiency and it took about a year to regulate my medications and find what worked best for me which was spironolactone and lisinopril hdtz and did well for a number of years up until I went off the medications and had a hard time finding a physician to put me back on them. But during that time only my right calf and ankle would swell and was when I developed the pigmentation on my feet and ankles.
