Itchy Rash: Red, Raised, Itchy bumps sounds like a description of hives. Usually oral steroids improve a hive-like rash. This type of rash can be brought on by recent viral infections, food ingestion or drug ingestion. There are, however, many causes of rash in a 3 year old child so seeing the rash would be helpful to assist in diagnosis. I would be happy to consult with your nephews mom as I am in Ohio. ...Read more

Got a rash on legs knees elbows and buttocks from being at the beach today. Any ideas what caused this? Not itchy- but looked like hives.

Got a rash on legs knees elbows and buttocks from being at the beach today. Any ideas what caused this? Not itchy- but looked like hives.

Beach Rash: Several factors can cause you to be itchy after a trip to the beach. Bugs, like sand fleas and the mosquito, are not uncommon on some beaches. The sand itself can cause irritations, especially to sensitive skin or freshly shaved skin. Another cause could be sweat dermatitis, which is a rash caused when sweat is trapped in the skin. Itching and tiny red spots are a characteristic of this rash.

Hello, im getting hives on my knees and elbows they are really itchy they are coming and going I also seem to have them on my ears.

Are they raised?: Hives are raised wheals and thus I wonder if your rash is really hives being confined to knees and elbows. I suppose hives from pressure can occur at these pressure points but they are not itchy. Please provide info related to duration and appearance of these "hives". In general, it is really difficult to tell what they may be without a picture and a more detailed description. ...Read more
