In May of this year, I spent 5 days in the hospital with cellulitis (sp) in my left lower leg. The antibiotics seemed to work, but I don t think that the swelling ever completely went away. Now, over the last couple days, I ve noticed a warm, red, very tender, even painful area above that knee & continuing up my inner thigh. It has become painful just to walk & I can feel it when I m just laying down.
