Thanks for your consultation at DoctorSpring.com.
I would be glad to help you with your concern. However, it would be better for me to see the rash and then give my opinion regarding it.
In dermatology, it is important to see the lesion to come to a diagnosis, hence i would like to request you to send a picture. You can add the same as follow-up question. You are welcome to add more details, if needed.
Looking forward to your reply. Take care
