The symptoms of prickly heat tend to appear after a few days of being exposed to hot temperatures. However, sometimes the symptoms may not appear for several weeks, or months.
Prickly heat causes a rash to form on your skin. The rash is normally made up of tiny spots, or bumps, surrounded by a patch of red skin. Sometimes, the spots look like tiny blisters. This rash may cause:
- mild swelling,
- itching, and
- a stinging or intense prickling sensation.
The rash can affect any part of your body, but most commonly appears on your:
- back,
- abdomen,
- neck,
- upper chest,
- groin,
- armpits,
- hands, or
- feet.
If you have prickly heat, your symptoms will usually be worse on the areas of your body which are covered by clothing. This is because your clothing can cause friction, and will make you sweat more frequently.
Babies and rashes
If your baby has a rash, and they appear to be unwell, speak to your GP, or contact NHS Direct on 0845 4647 for advice. Heat rash is a very common condition in babies, and will not cause them any serious harm. However, if you are at all concerned, your GP will be able to confirm the cause of your baby's rash, and provide any appropriate treatment.
