what cause hand sores
Hand-dermatitis?: Red sores all over the palm of hands are more often caused by a contact allergy, hand-dermatitis (eczema), or infections such as scabies. The diagnosis is needed as the treatment will differ based on the cause. A certain virus can cause sores on the hands as a part of hand-foot-mouth disease.
Hand-foot syndrome is a reaction that occurs with certain chemotherapy drugs when they leak into the tissues of the hands and feet, causing irritation and inflammation of the tissues. If it becomes serious, it can lead to peeling and blisters and can be very painful. If you have this condition, it's important to tell your doctor right away. Your doctor may choose to decrease your chemotherapy dosage or postpone a chemo treatment if you're having a severe reaction. Icing your hands and feet can help; also avoid washing dishes in hot water or putting pressure on hands by squeezing tools.
