Knowing how to treat blisters depends on where it’s located on the body. A blister is caused when fluid builds up under the upper layers of the skin due to damage by force or rubbing. Common blisters occur on the hands and feet and if they are not properly healed, they can lead to more serious complications, such as an ulceration or infection.
- Bandages of various sizes
- Antibiotic cream
Avoid breaking the blister. Treating blisters depends on its size. Try not to pop or break a small blister–just leave it alone. If you must cover it, do so with a loose bandage and be sure it doesn’t touch the blister. If a bandage is wrapped too tight, it can lead to swelling, numbness, tingling or pain, which is counterproductive in healing blisters.
- Larger blisters may break on their own. If this happens, wash your hands thoroughly before touching the affected area. Blisters can become easily infected and should be cleaned thoroughly. Do not put alcohol on blisters because it can delay the healing time. Many times, blisters will heal on their own without any topical treatment.
- Larger blisters may also cause pressure and pain and in these cases you may want to drain them. Sterilize a needle with rubbing alcohol and gently puncture the edge of the blister. Squeeze the fluid with your finger towards to hole in the blister and drain all the fluid out. Wash the area gently and pat it try with a piece of gauze.
- The outer skin of the blister should be left on unless it’s extremely dirty and can cause an infection. Apply an antibiotic cream to the top of the blister and smooth it flat. Apply a loose bandage or gauze to the area and change it once a day until healed. If the bandage gets wet, it will also need to be changed. This helps prevent any infections.
If the blister is on your foot, refrain from wearing shoes that rub or put pressure on it until it’s healed. Check the blister daily for signs of infection, such as increased pain, swelling, fever, redness, red streaks coming off the blister and any drainage of pus.
