Blisters are fluid-filled bumps that look like bubbles on the skin. You may develop a blister on your foot when you wear new shoes that rub against your skin or on your hand when you work in the garden without wearing gloves. Home treatment is often all that is needed for this type of blister.
Other types of injuries to the skin that may cause a blister include:
Infection can cause either a single blister or clusters of blisters.
Inflammation may cause skin blisters.
Occasionally a prescription or nonprescription medicine or ointment can cause blisters. The blisters may be small or large and usually occur with reddened, itchy skin. If the blisters are not severe and you do not have other symptoms, stopping the use of the medicine or ointment may be all that is needed. Blisters may also occur as a symptom of a toxic reaction to a medicine. This reaction is called Stevens-Johnson syndrome. Blisters that occur with other signs of illness, such as a fever or chills, may mean a more serious problem.
Check your symptoms to decide if and when you should see a doctor.
Most blisters heal on their own. Home treatment may help decrease pain, prevent infection, and help heal large or broken blisters.
Watch for a skin infection while your blister is healing. Signs of infection include:
Home remedies may relieve itching from blisters. One way to help decrease itching is to keep the itchy area cool and wet. Apply a washcloth that has been soaked in ice water, or get in a cool tub or shower.
