How To Treat Blood Blisters on Feet

Blisters are small sacks of fluid that builds up within the upper layers of skin. Blood blisters on feet will usually occur from the rubbing of shoes that fit poorly or improperly.  They can also occur from other forms of friction, infections, freezing, burns, or chemical exposure. Wearing a pair of shoes for an extended period of time can cause a painful blister. There are several remedies for curing blisters, as well as preventive measures that can be taken to keep them on feet from forming.

What is it?

Basically, a blister is a sac that is filled with a clear fluid. If it is infected, it can be filled with pus. Blisters on the feet will have more chances of getting infected than blisters on other parts of the body. They can make walking difficult and painful.


Some people wonder if they should prick a blister when it occurs. It is always better not to prick the blister, but if it is on a part of the foot that affects walking, or if it is very large, then it almost has to be drained.

If a blister must be pricked, disinfect it and the area surrounding it. Use alcohol to disinfect the area. For the instrument used to prick it, heat such as a flame is better than alcohol for disinfecting. Hold the instrument, such as a pin or razor blade, in the flame until it glows red hot. Then prick the side of the blister, and do not pull off the skin. It will act as a natural bandage for the condition.

Antibacterial ointment should be applied to blisters on your feet to keep them from getting infected, and the ointment should be used until the blisters heal. Keep the blisters covered with a bandage. Try to cover the blister without the bandage actually touching the affected area so that air can circulate, as the air will help to heal the blister. Soaking the feet in warm water will help to soften and shrink it.

Keep it covered. Remember, a blister should be healing each day. A sign of infection is when the fluid is not clear and has an odor. Seek medical attention if there is redness, swelling, or increased pain around the blister area, or if there are signs of infection.


Blisters on feet can be easily prevented. One way is to wear socks. Socks will protect the foot from rubbing against shoes, especially the back of the heel. Wearing a footie sock will also prevent the development of a blood blister.

Use powder on the feet before putting on socks so that the foot glides in the sock and does not rub against the shoe. If walking or running long distances, use petroleum jelly to coat areas of the foot that usually get blisters to cut down on friction.

New socks and/or new shoes might be necessary if the shoes are rubbing against the foot. Using acrylic socks might also help since they are made in layers that absorb friction.
