Dermatology Questions? Ask an Online Dermatologist.
Hi and thanks for query,
I would suggest you must visit a dermatologist to have thorough examination and to diagnose the cause of the condition as it seems to be dermatitis. You might need hydrocortisone in appropriate doses according to the severity of the condition and you can not stop hydrocortisone abruptly so you need to see a dermatologist to have an appropriate treatment. Meanwhile keep the area moist and avoid scratching it.
Let me know if you have further questions.
