While there are no major complications from swimmer’s itch, there are a couple of cautionary points to keep in mind. Firstly, if blisters develop, visit a dermatologist immediately. While swimmer’s itch is likely to clear up in a week or so, blistering may lead to scarring, which could take longer to resolve or leave unwanted marks. Secondly, the severity of the immune response varies from person to person. Those who have experienced swimmer’s itch before will have a quicker immune response the next time.
