I have developed skin allergy some 5 months back. My skin becomes very itchy (mostly on palms and feet). It turns bumpy red and then swelling starts. I tried to observe the reasons for it. But as far as I can relate it might be mostly because of dust. I tried to go to dermatologist but everywhere I was given levocetirizine. Have been taking that since feb 2020 (took two med of avil too) now i'm facing sudden problems like acute stomach pain, low blood pressure and once I fainted too.
