If its contact or irritatnt dermatitis then you need to be away from that particular stimulus. As to be sure for diagnosis it is needef photos of lesion, you can have online consultation with the dermatologist in out site from the option on the side of screen. You would get appropriate opinion from there. Hope it will solve your query.
