What causes blisters?

There are many different kinds of blisters and the causes of it are described below:

1. Cause of Blood blisters: 

This type of blister can be caused due to pinching of a substance or object to the skin which is a clear fluid with blood in it. The blood floods from broken blood vessels and damages the skin layers and this forms blisters.

Blisters symptoms

Generally, blisters do not need any treatments as some blisters heal by themselves and disappear while some blisters like frostbite need treatments. But if you have the symptoms like yellowish or greenish pus-like discharge, redness, or pain near the blistered areas, then this is a sign of concern and it is necessary to consult a specialist or doctor when this symptom persists. Always see a doctor when you have red swollen skin and if the blisters do not go away by themselves.

Blisters treatment

Usually, blisters heal by themselves and do not require any treatments or diagnosis unless an infection occurs. The regeneration of the blister on the skin forms new skin naturally by the white fluid and will peel off the old skin thus creating a new one. You should not pop off blisters as that can lead to further infection.

The swollen part is the barrier to that blister; removing it can lead to bacterial invasion. So it's better to cover those blisters with a band-aid or protective layers. If the blisters get removed or burst by themselves, then let it drain the fluid naturally without irritating and thus clean the dead skin cells or that area with water and apply some dressing on that or apply some medicated ointments as it would further not irritate the skin. 

Blood blisters also heal by themselves but they take time to heal them. Blisters can go away by themselves and also if you want to take some care of the skin, just wash the affected area with mild wash and apply an antibacterial cream or ointment if available at home. Then cover the area with a bandage or any covering thus protecting it from any further irritation. Remember to change the covering once in a while a day.

How can I prevent a blister?

You can prevent friction blisters by preventing the friction between your skin and the shoes or any object that your skin gets rubbed with. Wearing socks or avoiding tight wearing shoes will help get friction blisters on the feet. Wearing gloves on your hands would help you from getting blisters on the palm of your hands while doing labor work or any machinery tool work.
