Ok it's my own fault, I neglect my feet and go barefoot as much as I can around the house, preferring to wear "jesus-type" sandals all summer. I've got away with it so far, but now I have a problem with a sore crack on the underside of my right foot, below the ball of my big toe. It's sore. I've put savlon cream on it a few times today but keeping it clean where it is, is proving difficult. Should I go see the GP/nurse with this, given that I'm T1D 35yrs? Or just continue putting savlon cream on it and hope for the best?
