Thanks for the query.
Kindly meet a Dermatologist near you for diagnosis and treatment plans. Similar presentation can be seen in many skin diseases and can be diagnosed during a consultation. Over the counter (OTC) anti-allergic medications may be useful till then, but consultation should not be delayed too much.
Next Steps
Your dermatologist will decide a treatment plan for you after a consultation.
