Hi,
Welcome to health care magic,
Thank you for the query.
Your History suggests that you could be suffering from
Pityriasis rosea, which is a scaly
skin rash but the cause remains unknown and it is not contagious.
It has to be confirmed, kindly get yourself examined by a
Dermatologist so that he/she may examine you and suggest a blood works and
Skin biopsy to rule out other causes with similar symptoms.
Once confirmed you will be treated accordingly with medications and
Phototherapy if the symptoms worsen.
However, it may be better if you can send across a picture of the lesion. Follow these lifestyle modifications:
1.) Use lukewarm water when you shower or bathe, because it is less irritating.
2.) If you have itching, use calamine lotion.
3.) Stick to your treatment plan and go for regular follow up.
Hope I have answered your query.
Wish you Good Health.
Regards,
