I have developed sores on my feet and need to have it checked by a foot doctor which is scaring me in itself but I fear an infection. I think for me it is cause my feet are swelling and then my shoes rub. Do you think maybe your shoes are rubbing? Have you tried wearing a different pair or different sock? Do you swell? I was reading about diabetics having issues with sores on their feet as well. Not sure if you have that. What kind of doctor did you ask about this?
