Because of the condition of the skin and the swelling, it is fairly common for people with lymphedema to experience blisters. It is important to treat these correctly as they can be an opening for bacteria.
A blister is a lfuid filled “bump” or “bubble on the skin. It is an inflammatory response to skin trauma, injury or damage and is your body’s way of helping protect the injured area and to help it heal.
This bubble is basically a thin-skinned sac of a blister contains fluid, and in most cases should not be ruptured, as rupturing can introduce infection and slow the healing process. Blisters that contain blood instead of fluid are aptly named blood blisters, and are caused by a rupture of blood vessels beneath the surface of the skin, usually due to trauma.
Friction, constant rubbing and pressure are the most common causes of blisters. But there are many medical conditions that cause them as well.
These include:
Other types of injuries to the skin that may cause a blister include:
Some spider bites, such as a bite from a brown recluse spider . Symptoms of a brown recluse spider bite include reddened skin followed by a blister that forms at the bite site, pain and itching, and an open sore with a breakdown of tissue (necrosis) that develops within a few hours to 3 to 4 days following the bite. This sore may take months to heal.
Important point (1) - for people with lymphedema to understand that blisters should not be popped if at all possible. Left alone, blisters will generally self heal. Popping them is dangerous as it provides anopen door to a bacterial infection.
Important point (2) - If you have diabetes and lymphedema, special care must be taken as you risk of an infection is dramatically increased. If the blister is large, sore or red, you should contact you doctor.
Important point (3) – Many of us because of other medical conditions, for example cancer, may have a suppressed immune system. It is even more critical for you to correctly treat the blister, prevent it from popping and becoming infected. Sepsis, a life threatening infection could result.
Signs of infection could include:
If you have any indication of infection, contact your doctor immediately. Antibiotics need to be started immediately as well.
If the blister appears infected, it should be opened (preferably by a doctor) and drained entirely, an appropriate dressing and ointment applied, and the victim treated with antibiotics. Dicloxacillin, erythromycin, cephalexin, or augment are good antibiotics commonly used. The treatment needs to be for a miminum 5 days or until the skin appears normal. Complete the course prescribed by your doctor. Do not stop taking the antibiotic until the prescription is finished.
Preferably this should be done by your doctor. I understand some of us hate going to a doctor or think we can handle it ourselves.
These guidelines should be followed: (1)
Look for signs of infection to develop. These include pus drainage, red or warm skin surrounding the blister, or red streaks leading away from the blister.(1)
Blood Blisters - contain small amounts of blood that have accumulated from small broken capillaries or vessels within the skin. These skin blisters are typically characterized by excess swelling. Most commonly created due to an injury surrounding the skin caused by impact, a blood blister will typically appear deep red in color.
Fever Blisters - occur on the mouth and may be accompanied by cold sores or develop on their own. This type of blister is caused by a virus and may be contagious. The herpes virus also causes fever blisters and cold sores and is actually quite common. Blisters of this nature may cause skin irritation and burning. Itching and peeling is also common. Fever blisters are best left to heal on their own without any intervention or treatment.
Water Blisters - contain clear liquid and are typically small in size. Most often, these types of blisters are caused by chafing and irritation against an area of the skin. May people suffer from water blisters due to wearing improperly fitted shoes, and runners and athletes are typically prone to this. Water blisters are generally harmless and mild and most require no treatment, other than to keep the area clean and free of friction.

Bullae or Bulla are blisters larger than 1 centimeter wide. Bullae that are filled with clear fluid may occur on the skin.
Vesicle A vesicle is a small fluid-filled blister. A vesicle is small – it may be as tiny as the top of a pin or up to 5 or 10 millimeters wide.
In many cases, vesicles break easily and release their fluid onto the skin. When this fluid dries, yellow crusts may remain on the skin surface.
