What it is
The rash usually clears without scarring within about 2 weeks if the skin is kept out of the sun.
Sunscreen, covering up and slowly increasing sun exposure in spring can help. Steroid creams, antihistamines or light therapy (desensitisation) may be offered.
Common signs
- An itchy rash of small bumps or blisters
- Red, raised patches
- Burning or stinging skin
- Rash on skin exposed to the sun
How it is usually diagnosed
- Questions about when the rash appears
- Looking at the rash
- Sometimes blood tests or light testing to rule out other conditions
Records worth keeping
Keeping these together makes each appointment easier, especially when you see a new doctor:
- GP or dermatology notes
- Photos of the rash
- Blood test results
- Light therapy records
Questions to ask your doctor
- Could this be another condition such as lupus?
- Which sunscreen do you recommend?
- Would light therapy help me?
When to get help right away
