I'm 49y/o female with ESRF and on dialysis. I've had a foot problem for past month that podiatrist has been treating as gout but it has not gotten any better. Problem started with a patch of red, painful to the touch, just underneath the two toes after the big toe on left foot. It went from red to black and blue in middle surrounded by red skin. It is painful, stinging pain and bone pain and stiffness in two toes. I've had the foot swell up, twice, which eventually went away upon taking diclofenac and colcrys. Pain, stinging and bone, still persist. I've attached pictures of foot. Help please. Thanks.
