Vesicular rashes are bubbles or blisters that develop on the skin due to a viral infection. It develops on almost any areas of the skin of the body. This rash may also develop on skin areas that have mucous membrane present.
The term of “vesicular” is derived from the Latin word “vesiculum” that means “small bag”. Vesicular rash got its name from the appearance of sacs or vesicles on the body.
Vesicular rash may develop on any region of the skin. Vesicular rash can be seen on the legs, hands as well as the face. There are certain cases of Vesicular rash where the mouth is affected as well, due to the fact that in the mouth there is mucous membrane. The lining of the mouth or Buccal Mucosa is affected in these circumstances. In these rashes the area of the trunk is full of red blisters.
The disease is marked by the appearance of small rashes all over the body. The rashes are very itchy. If scratched, they may create scars on the skin. The rashes are seen as sacs elevated on the skin. This elevation is because of the fact that they are full of serous fluids.
Vesicular rashes that are caused by Herpes Zoster are linked with headache in individuals.
If the patient is suffering from Dermatophytid, there can also be fever along with the Vesicular rash. Dermatophytid is a reaction that is allergic to fungal infection. Vesicular rash and fever is common in patients with Dermatophytid.
In rashes caused by Herpes Zoster, individuals also have a physical discomfort that could involve depression.
The rashes are also very painful in some cases. The pain stays until the rashes completely go away.
In many cases, the rashes might change color and become darkened or even cloudy in appearance. This occurs in advance stages when the sacs are filled with blood. In the later stages, scales or crusts form over the vesicles. These ultimately fall off after a while and the skin will start to heal from that point on.
