Thanks for the query. Thats a very limited description to make any comments. I suggest you to see a dermatologist for a diagnosis and treatment plan. Delaying may not be a good option unless you know what the diagnosis is. Hope it helps you.
Next Steps
You can meet a qualified Dermatologist with MD/DNB/DDVL/DVD degree for proper examination.
