My daughter has just about the same as you. She has had them on and off for the past year. The doctor said it was a fungus. Watch to see if they turn white as though you have had a sun burn. Hers does not itch and it only on her arms, stomach, back, neck and shoulders. Please let us know what you find out. Thanks. ***@****
Without examination,confirmation of a diagnosis is tough but it can be pityriasis rosea or pityriasis versicolor.
Pityriasis rosea is a common human skin disease which presents as numerous patches of pink or red oval rash. The rash may be accompanied by low-grade headache, fever, nausea and fatigue and sometimes by itching.
No treatment is usually required. In most patients, the condition lasts only a matter of weeks or months (upto six months)
If the rash persists then it will be best to get it evaluated from a dermatologist. Other possibilities have to be ruled out then.
I hope that helps. Take care and please do keep me posted in case you have any additional doubts. Kind regards.
