Some diseases, conditions, and health problems have clear-cut symptoms. If you have arthritis, your joints hurt. Parkinson’s causes tremors. Heart attack, stroke, and even a urinary tract infection are accompanied by recognizable, tell-tale signs. Such is not always the case with peripheral artery disease (PAD). Its symptoms are often ambiguous, which means that sometimes we have to perform tests to rule out other issues – and no patient likes to be poked or prodded more than necessary.
