What should I do if my hands and feet are red and rash after sleeping abroad for one night?

I think it may be eczema or allergies. I have allergic skin, specifically, I love allergies. If the swimming water is not clean, I will itch. I think the landlord may be like me, so I go to the hotel to stay, no matter how many stars, I bring my own sheets. Are you still serious? I think you can observe it first and disappear in a few days. If it's still serious, take some Piyanping after taking a shower. If you are not at ease, you can have a small examination in the hospital. I think it's just that the hotel is humid, or his sheets are not clean and disinfection is not thorough. Don't worry too much, just watch!
