Hello and welcome to the forum. We appreciate your question and this sounds like a frustrating situation to have. We always recommend being seen by a doctor. This is going on in both legs, correct? Something to look into is called claudication. This is a lack of blood flow and can sometimes be felt in the calf upon walking or exertion such as you describe. When claudication happens in the legs, it is normally a result of peripheral artery disease which is when plaque builds up in these arteries. You don't mention your weight or age or general health status but lifestyle changes can help if you are obese, a smoker, have high cholesterol, blood pressure or diabetes. Improvement in any of those areas helps with peripheral artery disease. This is by no means a suggestion that you have this but that it is a possibility that you can check with your physician about. Here is more information explaining it: https://www.webmd.com/heart-disease/intermittent-claudication#1
