Exams and Tests
Your health care provider can often make this diagnosis based on looking at the rash and knowing that you have been in a hot tub. Testing is usually not needed.
Treatment may not be needed. The mild form of the disease often clears on its own. Anti-itch medicines may be used to ease discomfort.
In severe cases, your health care provider may prescribe an antibiotic.
This condition usually clears without scarring. The problem may come back if you use the hot tub again before it has been cleaned.
Discomfort and abscess formation can rarely occur.
When to Contact a Medical Professional
Call your health care provider if you develop symptoms of hot tub folliculitis.
Controlling the acid levels and chlorine content of the hot tub may help prevent the problem.
