Blisters are painful, fluid-filled lesions produced by friction and pressure. They can be caused by the following:
Blisters can become a more serious concern if you have diabetes and may not heal so easily. Please refer to your podiatrist for further advice.
As blisters are the result of friction, there are a number of simple techniques that can prevent your walking, running or social activity being ruined by a blister:
It is possible to buy socks made of fibres with good ‘wicking’ properties and also special ‘dual layer’ socks where the inner layer moves with the foot, the outer layer with the shoe – eliminating friction at the skin surface.
It is important to act immediately if you feel any friction or discomfort as blisters can form very quickly. Stop walking or running and examine your feet and if nothing has developed, consider applying some material or padding to cushion the area or even a breathable waterproof plaster. If a blister does occur, do not pop it. Cut a hole in a piece foam or felt to form a doughnut over the blister. Tape the foam or felt in place or cover with a soft gel-type dressing. Treat an open blister with mild soap and water, cover it with an antiseptic ointment and a protective soft gel dressing to prevent infection and speed up the healing process. Most foot blisters last between three and seven days and will normally clear up if further excessive friction is avoided.
If you experience any foot care issues which do not resolve themselves naturally or through routine foot care within three weeks, it is recommended to seek the help of a healthcare professional such as your GP to refer you to your local NHS trust for free treatment but if you do not qualify for this, or need urgent attention, you should contact a private podiatrist. To talk to a podiatrist (also known as a chiropodist) about the options available regarding treatment, you can contact an NHS podiatrist or a private practice podiatrist. In both cases, always ensure that any practitioners you visit are registered with the Health Professionals Council (HPC) and describe themselves as a podiatrist (or chiropodist).
