Rash: So many things cause rash. Skin is the largest organ in/on the body. To get the best diagnosis for a rash of any kind, it is recommended to have a doctor look at the rash to confirm and provide appropriate treatment based on the evaluation. Infections, irritation, allergy, medications, etc can all contribute to rash.

Skin rash : Contact dermatitis is an allergic skin rash caused by something touching the skin that the child is allergic or sensitive to. Examples might include lotions, fabric softeners, & certain fabrics like wool. In older children nickle (in earrings and metal snaps) can cause a very localized contact dermatitis. The rash associated with poison ivy is one of the more severe forms of contact dermatitis.

Hives/spreading fast: If your baby has a sudden onset of raised hives/severely itchy rash all over the body that continues to spread quickly, it may be a sign of a severe allergic reaction. Also any purple or black looking spotted rash, especially associated with fever, vomiting, and ill-appearing child could be a sign of a life-threatening rash.

A 16-year-old female asked:

For a few years now i continuously get a rash around my lips. It is not constant but always occurs at random times. any ideas as to what is causing it?

Some thoughts...: Persistent chapped lips may be lip eczema, which can be treated like skin eczema, using Hydrocortisone cream, plus vaseline or Aquaphor to moisturize. Sometimes, lipsticks or lip sunscreen chemicals are causing an allergic reaction on the lips. Other times, a person is a primary lip-licker (it's her habit). Once cracked, lips get irritated by routine foods and juices. A doctor can sort things out.
