Usually, bumps on the hands caused by eczema are not contagious and there is no need for patients to stress. However, if they are contagious, such as warts, patients should seek medical attention and do not use medication blindly to recover as soon as possible. During the treatment period, you need to use separate towels, avoid skin-to-skin contact with family members, separate utensils such as cutlery and washbasins, and try not to shed dead skin from your palms in areas where family members often move.
