Hello,
Without examination,confirmation of a diagnosis is tough but it can be discoid eczema ,pityriasis rosea, or ringworm.
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.
Hope it helps.Take care and pls do keep me posted on how you are doing or if you have any additional queries.Warm regards.
Very smart dj150. erythema centrifugum is caused by tick bite ,but it will have a central punctum of the bite.
