It is important to note that skin blisters usually manifest as circular, elevated areas of fluid that gather under the upper skin layer. The fluid or serum can range from clear to yellow and originates from the damaged blood vessels. The blisters develop as a way to protect the damaged skin from further injury. The skin blisters manifest due to various reasons including diseases as well as external factors.
The skin blisters oftentimes form on sunburned skin. The symptoms of sunburn usually manifest within several hours of extended and intense exposure to the sun and typically vanish without requiring medical care within several weeks. The blisters from sunburn are small in size and filled with clear liquid. A doctor can be consulted if the blisters break open and drain yellowish pus.
Impetigo is considered as a fairly common skin infection due to bacteria such as streptococcus, Methicillin-resistant staph aureus (MRSA) or staphylococcus. The symptoms of this skin condition include the development of one or several blisters filled with pus. These blisters are likely to itch and ooze yellow to yellow-brown liquid. This infectious disease can spread through this fluid. Cases of mild impetigo usually respond well to prescription antibacterial creams while severe cases often require oral antibiotic medications.
Chickenpox and shingles
Both chickenpox and shingles are caused by the varicella-zoster virus. Chickenpox is a common childhood disease that causes the formation of several fluid-filled blisters. These are intensely itchy blisters that generally turn cloudy in appearance within 2 days, after which they break open and turn crusty.
Some adults will develop shingles infection once the chickenpox virus reemerges during times of extreme stress. Take note that shingles or herpes zoster involves an itchy, blistering rash. The fluid-filled blisters pop, creating small-sized lesions that later on dry out and crust over. Even though most cases of chickenpox and shingles should run their full course, doctors might prescribe antiviral medications for severe cases.
Atopic eczema is a lingering skin condition that involves itchy rashes and blistering skin. This condition develops once the skin overly reacts to a specific stimulus and develops long-term inflammation. The usual triggers include pollen, animal dander, house dust, mold, pollen and extreme temperatures. Certain foods can cause eczema flare-ups such as eggs, wheat, peanuts and dairy. The blisters that develop with the rashes usually ooze liquid and eventually crust over.
This condition causes a chronic, blistering rash. Dermatitis herpetiformis is also called as Duhring’s disease can cause intensely itchy skin blisters that develop on the buttocks, back, elbows and knees. The exact cause of this skin condition is still unknown but there is a possible link with gluten sensitivity. Those who have this condition often respond well to a gluten-free diet that is accompanied by doses of prescribed antibiotics.
