I have been getting a heating sensation in my left leg from the knee to the ankle
went for a a scan no blood clog
Heating sensation can be caused by damage to nerves in the legs, exposure to toxic substances, alcoholism and diabetes. Blood clogging may be absent but you should go and have other checkups with your doctor.
Blood clot is usually a smaller, concentrated point of heat and a general pain. You may have injured/torn/strained a muscle, especially if the heat follows one of the muscles or tendons in your leg.
