Aquadynia is a big word that means pain when you touch water. Have you ever been in a pool or a bath and your skin feels like it's prickling or burning? That's what aquadynia is. It's a very rare condition where your skin hurts when it's in contact with water.
It's like how some people can't drink milk because it makes their tummy hurt. Except for people with aquadynia, it's water that makes their skin hurt. Aquadynia can happen all over your body, or just in certain areas like your hands or feet.
Sometimes doctors aren't sure why someone has aquadynia, but sometimes it can be because you have a skin disease or an allergy. It can be really uncomfortable to have aquadynia, but doctors can help manage the pain with special creams or medications.
