I was diagnosed with kidney cancer this past spring and had a right radial nephrectomy- patho revealed clear margins. YAY! After my surgery I have been paying attention more to drinking lots of water, protecting the kidneys, signs of kidney failure. My shoes have been feeling tight, in particular, my right shoe. I ve even had to move up a size in shoes. No signs of swelling are present. However, tonight I realized that my right foot is now about 1 inch longer than my left foot!! This has never been like that before. I am 31 years old and have worn the same size shoes with no problems since the 7th grade. What s happening?
