Hello, You have heat sensation on the right calf & knee. It causes you discomfort. Such symptom can be the beginning of peripheral arterial disease. It commonly starts due to the narrowing of the blood vessels. When left untreated, it may cause accumulation of fat in the (arteriosclerosis), resulting in decreased blood flow to vital organs like limbs, heart and brain. The risk factors like diabetes, high cholesterol and blood pressure, obesity, smoking should be kept under control at all cost. Other risk factors are family history of cardiovascular disease, stroke or peripheral artery disease. You are suggested to get clinically examined by a GP and get a complete health check up done to avoid illness like vasculitis, deep vein thrombosis, restless leg syndrome in the near future. If diabetic control blood glucose, if suffering from high blood pressure, high cholesterol, etc., get treated so that risk of suffering a heart attack or stroke caused by arteriosclerosis is reduced. Switch to healthy lifestyle, take home made healthy food, do regular walking. Sleep in time, do not stress, maintain your vitals by better eating habits. Stay away from addictions if any. Take care.
