In all likelihood, you have managed to burn your hands very badly by getting this much bleach into them. If you have blisters, then you probably have second degree burns. It is important for you to know that it may not be possible for you to treat these successfully and properly at home. Sometimes, burns have a tendency to get infected if not taken care of in a proper and timely manner. If you have spent four days without relief of any kind, it is likely that you have managed to get an infection. Just be on the safe side, you should get a medical examination in order to make sure of the extent of your injuries.
If you want to take care of them at home, however, you can follow some simple methods for relief. To begin with, you can apply simple white minty toothpaste to your burns. Toothpaste has cooling menthol which will absorb excessive heat from your burns. This will make the temperature of your skin come down, which will in turn help your burns to heal faster and will also provide relief from the itching and burning sensation. You can also apply cool yogurt to your burns for relief from the itching and burning. Though yogurt may not be of any use in healing, it will certainly give relief. You can also make a paste of fresh mint leaves and add it to the yogurt. This combination will be particularly helpful in providing relief from the intense burning. You can also dip your hands in cool milk for relief. Keep them in milk for half an hour or so, and keep adding ice cubes to it. This will also provide relief, and will also help you to heal faster and better. Apply olive oil to your hands to reduce the burning.
