MY legs are stiff--the upper part in the front. I have had this problem for twenty years but it s worse now. Sometimes my legs are awkward from the stiffness. I need orthotics in my shoes, and I have some toenail fungus. Heat feels good on my legs. I am 86 years old but mostly healthy, active and happy. I can easily do exercises though I don t like to walk for very far because of my legs.edith
