Hello, I have a rash like thing on my hand and have had it for about two weeks. I m practicing dental assisting so we come in contact with lots of disinfectants, some saying they can cause contact dermatitis. Honestly, sometimes I did forget to wear gloves but I started protecting the area and putting on calamine lorion on it but it s still on my hand and it s starting to annoy me. It s sensitive, a little bit raw, a light red and bumpy. But it s like in one area only. The rest of my hand of soft and perfectly fine.
