I feel like I have worked out my legs, they are sore. Mostly in my upper thighs and quad area. They have been for a few weeks, I feel all stiff when I sit, sometimes causing me to not be able to rise quickly. I am in the beginning stages of diabetes. I have gained a few, about 20 extra pound, but I don t believe I would be sore. I have had orthoscopic surgery on both knees and had rooster comb injections about 1 year ago.
