I woke up this morning, felt mild pain on my left heel and saw a crack in the skin with dried blood. A nearby area was slightly discolored and sore on touch. Is this something I should see a doctor for? I do have been feeling dehydrated lately due to being in a crash that's now ongoing for 4 days and that seems to affect fluid balance. According to last year's blood tests I don't have diabetes. I might have peripheral neuropathy but it's not been confirmed via testing.
