Small blisters can be caused by pinched tissue, inflammation, allergies, or repeated force. If they don’t clear up, see a doctor. Blisters due to immobility or unknown causes should also be examined.
Small blisters are often the result of pinched tissue in the underlying layer of skin, resulting in small red bumps appearing above the skin at the affected location. There are many other causes of tiny blisters, such as inflammation that occurs within the body and an allergic response to certain medications, foods, or substances in the environment. Repeated force against the skin can also cause small blisters in certain areas, such as the fingers if you use a pen or pencil incorrectly. If these tiny blisters don’t clear up on their own within a short period of time, it’s advisable to see a doctor.
Blisters that occur under and over the skin could be due to pinching of the underlying skin tissues, which can produce these small bumps. It’s wise to see a doctor if small blisters cover a large area of skin, to make sure the underlying tissues can heal properly. It is not uncommon for the skin to blister when the body is immobile in one position for an extended period of time. This can be due to sitting in a chair for many hours or resting in bed over a period of days or weeks.
Itchy blisters can occur in different places on the skin due to an allergic reaction to a certain food, drug or substance that an individual may come into contact with in the environment. Sometimes small blisters can be produced due to inflammation within the body, caused by a number of factors. Medications and diet can both cause some degree of inflammation within the body, depending on the individual and their specific state of health. Inflammation may be the first sign that the skin is attempting to heal itself, and blisters may clear up on their own.
Repeated aggravation in certain areas of the body can produce blisters and a slight level of inflammation within the underlying tissues. Incorrect or prolonged use of a pencil or pen can cause writing blisters to form on the sides of your fingers and hands. Unexplained small red blisters that are not linked to any known event should be examined by a doctor. Blisters that occur on their own may be the result of some type of viral infection or disorder in some individuals.
