I have problem of rashes on my skin of entire body. It get swell after itching. Also the body parts get red colored. Initially I had some medicine like-levocetirizine and allegra for allergy. It reduces itching for some time and when dosage were stopped itching came back. And the redness never went. Whenever I get exposed to dust it starts, whenever I bath it starts. Don't have any disease or any physical relationship.
