I am suffering from continuous itching all over my body since the past week now. It is not mosquito, I've found. The major changes recently are: 1. I had a flowing nose for which I took 2 levocetirizine tablets 2. I am having outside food recently, but nothing I knew that was allergic to me. I had grilled fish recently which I generally do not have frequently. 3. I shifted to a new flat which have quite a few cockroaches as of now. I am taking care of hygiene as much as I can though I think it is an allergic reaction, but not sure since I've never had one before.
