I have two bumps on the top of my foot. I know I dropped something on my foot a while back and it became this big bump. The other is similar. So when I went to the podiatrist recently, I asked him about it and he said it was arthritis. Arthritis? When I asked him what is arthritis (he offered no help for it, by the way), he practically yelled at me (first time I went to him) and loudly said, "Inflammation!" And then he proceeded to cut my toenails. Anyway, I stopped him from continuing working on me, and said I don't want him to continue. He said why. And I said because I don't like his attitude. So I got one foot with cut toenails, went into the nail salon and had a nice pedicure. :-)
