For the past few weeks I've experience high sensitivity in my calf to touch, got very pale with white spots until it was rubbed or I started walking to have it gone. Later, it got hot and experienced burning sensation. Few days ago my foot went numb especially around my toes and it feels swollen around my ankle. The pulling sensation inside is killing me as well as when I try to bend my leg behind the knee. Any idea what this is? Am I going to lose my foot or my leg because of this? Thanks!
