Question
Are there blisters appearing in other parts? Is the fluid inside the blisters cloudy or clear? Are there any signs of fever?
Answer
If your child has blisters only on the foot bottom and none elsewhere, and the fluid inside the blisters is clear, without any signs of fever, they may have a common simple viral blister. You can let your child take some antibiotics to reduce the height of blood vessels. For the issue of high blood sugar, further examination is needed. I hope this answer can be helpful to you, and wish you health!
