Heat Blisters Advice
If you are not sure about what the rash is, it is best to show it to a doctor. If your daughter is uncomfortable being examined in such a sensitive area, you should find a good female doctor and also reassure your daughter about the process.
In case it is a heat rash, it should be possible to get rid of it or at least reduce the severity quite easily. The mechanism behind heat rashes is similar to that of pimples – sweat glands get blocked by dead skin cells, dirt, and bacteria, leading to the tiny blister-like eruptions and irritation. Your daughter should avoid the heat as far as possible, and minimize activities that cause her to sweat. If she exercises or plays a sport, she should bathe and change her clothes, including underwear, as soon as she finishes. She should in fact bathe several times a day using cold water, and try using an antibacterial soap. It is very important to have a daily change of clothes, and since she has this problem, underwear should be changed twice a day. It is advisable to use only light cotton clothes, particularly underwear. If these measures do not work within 10 days, she should see a doctor.
