Summarize the following:
As difficult as it may be, leave your blisters alone and avoid scratching. They will crust over and then fall off on their own. If you scratch them, they will open up and become more susceptible to infection. You will also spread bacteria with your hands if you scratch at the blisters. If this does happen inadvertently, always wash your hands afterward to stay hygienic. Baking soda has a pH greater than 7 (making it alkaline), giving it the ability to neutralize the chemical that creates the itching sensation. The chemical creating the itching sensation is acidic with a pH that is less than 7.  Apply a paste made of 3 teaspoons baking soda mixed with 1 teaspoon of water. This relieves itching and helps the blisters dry out quicker. You can apply this paste as often as needed to relieve the itching. Use a cool, moist compress to ease discomfort. You can apply this compress for up to 20 minutes at a time, several times a day. You can make a cold compress by wrapping an ice block in a clean towel and pressing it against your skin. Alternatively, you can use a bag of frozen vegetables. Just make sure not to put it directly on your skin and not to keep it on your skin for more than 20 minutes at a time as both of these conditions can lead to tissue damage. Apply a topical cream, such as nonprescription benzocaine cream, directly after your cool compress application. Benzocaine works as an anesthetic, numbing the nerve endings in the skin. As an alternative, talk to your doctor about prescription 5% Lidocaine patches. You can apply the patch to the area where you're experiencing the pain, as long as your skin is intact. You can apply as many as 3 patches at once. You can wear your patches for up to 12 hours in a 24 hour period.

Summary:
Try to keep from scratching at your blisters. Use a baking soda paste to reduce irritation. Apply a cold compress to your blisters. Spread Benzocaine cream on your blisters after you remove the cold compress.
