Question: My 3-year-old daughter appears to have some kind of bite on two of her fingers. It itched for a couple of days, thenthe skin on those fingers seemed very hard, almost callouslike. Now the fingers look like there are little blisters on them and the are is peeling. The skin is still hard underneath also. I'm at a loss because I have no idea what it is or what bite her. I hope you have some advice for me.
It sounds like what you described....some sort of bite, possibly a very small
insect like an ant. It itched, so your daughter scratched it! This in turn caused
the hardened skin also known as a callous (callous). This is a typical reaction.
What may have happened, is that the skin that she was scratching became
infected and inflamed.
Once skin is broken, (first line of defense for infection) any number of
germs may cause infection. Bacteria such as Staph or Strep may cause
infection. Viruses, if present on the skin may also be the cause.
Red ants may cause a local reaction with blister formation. This is usually
what is called a sterile abscess. As the ant bites, it releases formic
acid, which is irritating and inflammatory to tissues. If these blisters are
not broken, it usually resolves on it's own. Infection occurs if these
blisters are broken.
Keeping the skin clean and applying topical antibiotic ointments will help
with the local infection. If it seems to be spreading or if there are other
signs of infection (pain, fever, swelling, etc.), please have it looked at by
your daughter's doctor immediately. "An ounce of prevention is worth a pound
Also see: My 12 year old daughter experiences difficulty sleeping due to fear of the dark and being alone. Is this normal?
What is the cause of ITP and is there anything that can prevent it from recurring?
