Definition
Bubbles are a group of skin changes that can occur for various reasons. They are fluid-filled elevations of the skin. Bubbles less than one centimetre in size are called blisters.
Bubbles can be located within the epidermis or under the epidermis and contain liquids of different quality. They can be tissue fluid with or without blood or inflammatory cells. They can also be found on different parts of the body, such as the face, mucous membranes, the trunk or exposed areas.
For example, some blisters appear in belt-like arrangements, others in groups or isolated. The surrounding skin can be inflamed and reddened. Itching or pain may also accompany the blisters.
Blisters on the hand can also be of various types. The hands are particularly exposed to mechanical and chemical stimuli. Fingers and fingertips are sensitively deeply innervated – therefore blisters on the hand can often be accompanied by pain. Itching and reddening of the hands is also often very pronounced.
Should one prick blisters on the hand?
Every day our hands come into contact with a multitude of pathogens and other impurities. A piercing of blisters on the hand should be avoided in any case. This can easily lead to inflammation, which makes the healing process more difficult. Contaminated blisters must be carefully disinfected. In any case, the uppermost layer of skin should be left on opened blisters; in addition, a plaster should cover the wound.
What can you do about it?
In the case of blisters on the hand caused by mechanical causes, further stress should be avoided at first. If possible, the blisters should not be opened as this can cause pathogens to enter and cause inflammation. The upper skin layer should not be removed under any circumstances, as it protects the sensitive skin layers underneath.
In addition, blister protection plasters can be applied to cover the area. As a preventive measure, care should be taken to protect the hands, especially moisture and friction favour the formation of blisters. If chronic skin eczema has occurred due to a contact allergy, a variety of preventive measures should be taken after consulting the dermatologist.
Symptoms
Blisters on the hands with a mechanical cause are usually skin ridges filled with clear liquid. Blood admixtures are also possible. The blisters on the hand are usually a few centimetres in size, depending on the strength and duration of the strain, and occur in places that have been subjected to unusually high strain.
At first the blisters are not inflamed and only slightly reddened, a slight pain under pressure or strain can occur. If the bladder opens or is opened, pathogens can penetrate and cause an inflammation. The deeper skin layers are very sensitive to pain.
The covering layers should therefore never be removed. With hand eczema, in addition to small blisters and tears, severe itching and reddened palms of the hands occur. The symptoms increase especially after contact with the allergen, but also independently of it.
