A while back my wife got a dark yellow spot on the top of her foot, now she has 2 lumps, one on each foot, her doctors say they don t see any thing abnormal in her CT Scan or X-Rays, say possibly arthritis. Now she has the same dark yellow spots on the sole of her feet. She is in pain most of the time she is on her feet. When she gets out of bed in the morning she says the pain is low, but as she walks around it starts to hurt more.
