question: My son had a blister on his big toe about 4 weeks ago. Since the blister has popped we have been unable to get his skin back to normal. He s had 3 deep cuts on his tiny big toe and the skin feels very rough like a callus. A couple of the cuts look fairly deep. We ve been putting medicine and trying to keep band-aids on his toe to get it healed. How do we get him back to normal? Should we be concerned?
