Causes and Treatment of Blisters


Blisters can be defined as tender, swollen, sacs of skin of different dimensions that are full of fluid or blood. These blisters are caused due to the constant rubbing or irritation. If the rubbing or friction continues unchecked, it may affect the small blood vessels which cause what is called ‘blood blister’.

Painful to the touch, blisters may occur on any part of the body but they mostly afflict feet. This happens because of sporting tight or uncomfortable shoes which do not fit the dimension, contour, or movement of foot, which triggers heavy rubbing on pressure points. It should be noted that toes and heels are the most susceptible parts of the foot where blisters are most likely to appear.

There is nothing to worry as this condition usually cures on its own. However, if the rubbing continues, the blister may endure for several weeks. As a matter of fact, blisters break early under the continued pressure that presses down the skin. When the blister breaks, the fluid drains on its own. At such time, it is imperative that care is taken so that no infection develops and that the sore doesn’t become a festering wound. If the friction is only mildly irritating, the blister would heal though sooner or later a callus will develop.

Generally, blisters heal within a few days even if left untreated. Therefore, the best alternative is to keep the area dry and clean. In case of the blister breaking, the area should be monitored to check any further damage or infection.  However, if the blister remains intact then a new layer of skin will automatically appear under the sore and the exterior skin will finally shed on its own.

As far as possible, guard the blister against breaking as the layer of skin covering the fluid is a natural protection against germs and infection. If the skin tears and fluid flows, simply wash the area gently with soap and water, quickly dry and apply an antibacterial ointment and a sterile bandage. Those suffering from diabetes should take special care of their feet and need intently inspect any developments in this area. They need to carefully monitor their feet every day.

Though blisters are very common and hardly anything to worry about, you need to seek medical care if you see pus or redness of skin or if your skin becomes more painful than before. You should immediately contact a healthcare provider if you are suffering from excessive blistering. You need to be extra careful particularly when  blisters irritate or if blisters occur on areas that are usually free from rubbing or friction, for these are signs of sickness, not any other skin itching.

However, you can lessen the severity of blisters and also prevent them by putting on socks that absorb wetness or perspiration. You should also be careful about the size of the shoes and avoid wearing too tight shoes. If you wear the shoes that are either too big or too small, they will cause friction and itching. If your foot-skin is too sensitive or if you suffer from any foot deformity that make your gait awkward, you should use shoe inserts that  help cushion, prop and balance the foot and thus lessen your chances of blisters.
