That is very interesting. I have had this, and really only feel it when I get a massage, for several months now. I think what is more accurate is close to a year.
I will go ahead and do something for my kidneys. I was eating Watermelon often, due to it being very available here. I guess it was not continuous enough though :/.
Thanks for the information. I, too, would like to be able to wear my shoes. Actually, I have a pair of shoe boots that I would love to be back in! :D
