Hello, The description you gave may be one of many skin conditions that have similar symptoms. Hence, it is not possible to prescribe any medications without having a look at the patches first. Hope you understand the limitations of a public online platform. Hope this helps.

Next Steps
consult a Dermatologist in person or on private chat so that a certain diagnosis can be made after having a look at lesions.
