I am getting these dark red blister looking things on my right foot only. They show up several at time, usually on the sides of my foot and in the arch. They are hard and don't seem to have any fluid in them. One day it will show up and in a week it will go away and there will be lots of dry skin to peel away. Now on the right side of my right foot there is a place the size of a nickel that must have been dark red at one time and now the skin has come off. Its hard for me to get to that side of my foot due to my weight but if i stretch my leg out I can see it. Well, last night I saw that it was like a patch of dry skin and it was like a couple of layers of skin had been removed and the "inside" of the spot had a red tint to it, like sunburn, not like a red blister, but it is sore. It never happens on my left foot. Do you know what this might be and how I should treat it? My friends daddy had diabetes and had a sore on his foot and later in life he had to have his legs amputated. This scares me. I have a doctors appointment in about 2 weeks, and will ask him then, but was wondering if I could get some advice here until then. Thank you.
