Treating blisters is an important part of feet hygiene, according to the FDA. Foot blisters are common symptoms of HFMD as per the CDC. Certain home remedies, if followed properly, can help cure blisters within a day or two. They are tried and tested remedies and can be very helpful. 
Medical Treatments for Blisters
In most cases, a little first aid treatment should be sufficient to treat the blister, other times, you may require antibiotics or other treatments.
For the first aid treatment:
- Take a needle and wipe it clean with alcohol;
- Pinch the blister with the needle;
- Press the fluid out towards the punctured area;
- Cover the area with gauze;
- Wait for it to heal.
Some precautions while administering first aid:
- If you see any signs of infection, i.e. yellow pus draining out, etc., then you should see a doctor.
- Do not drain out the blister if you are diabetic, HIV, cancer or heart patient as these are contagious.
- Use a donut-shaped moleskin pad for the affected area. Make sure not to cover the foot blister itself. This will prevent it from exploding on its own and causing a mess.
Vitamin E Pills
Another medical treatment for foot blisters is to use Vitamin E pills. For this, you can just pop open the pill and apply the liquid directly on your blister. This is because Vitamin E has amazing skin healing properties and will also prevent scarring. Lastly, if you aren’t up to date on your tetanus shots, then get one to avoid further complications.
Home Remedies for Foot Blisters
Home remedies for foot blisters can include the use or application of apple cider vinegar, castor oil, antibacterial ointment, pads, warm water, Vaseline or any petroleum gel, Aloe Vera gel and Epsom salt. These home remedies are very simple to use and assist in making you more comfortable if you have foot or hand blisters.
This is one of the simplest forms of home remedies available to treat foot blisters. Simply smear some castor oil on the affected part of the blister and leave it overnight. In the morning, you will notice that the blister has dried up completely. However, make sure not to peel off the upper layer of the skin, allow it to detach naturally, or the blister may reform.
Soak your feet in lukewarm water once a day at any time for about 15 minutes. This will help the upper layer on the blister to become soft, thus removing the fluid inside the blister and helping to cure it faster.
Apply any antibiotic ointment on the blister; it will help to cure the blister to a great extent. One can also make use of the antibiotic ointment in lukewarm water and soak the feet in this water for about 15-20 minutes. This will also help cure blisters.
Padding the blister will also help to a certain extent. One can make use of cotton while padding, leave the blister exposed, while the surrounding parts should be padded in a donut shape. This will help prevent bacteria from infecting the blister once it is broken. This remedy is very helpful if you get these blisters on the bottom of your feet.
Apple Cider Vinegar
Apple cider vinegar can be very effective and simple to use. Take the paste of a smashed onion, mix a spoonful of apple cider vinegar into it and apply the mixture on the blisters. This will help the blister to dry up very quickly.
Vaseline or Gel
Vaseline or any other petroleum gel can also help cure blisters. Apply it to the blister before going to bed to see a notable improvement by morning.
You can also use this remedy, as it has proven to be very useful, especially for burn blisters. Add some salt to the ice-cold water, soak a clean cloth in this water and rest the cloth on the blister. It will help the blister to compress and heal.
Aloe Vera is considered to be very effective and has been used since ancient times. Apply Aloe Vera gel on to the blister and it will lessen the pain and will help in drying the skin.
