While we all commonly call fluid filled sacs under our skin, blisters, not only is this a non-medial term but does not give any indication as to their cause. Medical professionals call small blisters vesicles if they are less than a third of an inch. If they are greater in size then they are called bullae. Your activities before the blisters appearance and the site of the blister often but not always are indicative of the cause. If the blister arose on your heel after wearing a new pair of stiletto high heeled shoes then friction is probably the culprit and shoe blister remedies are needed. Perhaps you tossed a hamburger into a pan with oil sizzling rather then slowly lowering the meat into a pan using tongs. The resultant blister will be from a hot oil heat burn. Other causes of blisters includes freezing the skin such as frostbite and chemical burns such as car battery acid. Occasionally blisters arise secondary to infections such as herpes cold sores on the lip or on genital skin. Staph aureus a bacteria commonly causes bullae or blisters on the skin known as bullous impetigo. Certain types of athletes foot fungal infections cause small vesicles or blister on feet. Blister also arise sometimes from some insect bites, particularly on the lower leg. Severe contact dermatitis as seen from poison ivy causes skin blistering. Rarely, bullae arise spontaneously from skin diseases where the immune system attacks the skin such as Bullous Pemphigoid.
The vast majorities of blisters are from obvious causes and can be prevented in the first place. Blister prevention will be covered in another blog. Regardless, if you need blood blister treatment, hand blister treatment or foot blister care, the following are suggested for all of the common blisters encountered. Even though tempting, do not pop the blister! The blister acts as a bandage and allows healing to proceed without giving a path for bacteria to gain access into the skin which may cause secondary infection, So despite the temptation, avoid popping a blister. A loose band aide or bandage protects the fragile blister before it pops spontaneously. A loose padding is sometimes used over pressure areas such as the bottom of the foot.
Occasionally the fluid in the blister is under a lot of tension causing pain or the blister may be so large that is interferes with activities. In this case, a pin can be sterilized with rubbing alcohol and an edge of the blister punctured to allow some fluid to drain.
Popped blister treatment is slightly different. Leave the blister roof in place and do not attempt to cut is away. This overlying skin acts as natures band aide and is chock full of your bodies natural antibiotics produced by the skin. Both protect the exposed skin as it heals. Keep the area clean. Do not be afraid to clean the area with tap water and gentle bar soap such as Basis. Afterwards, gently pat the area dry and apply OreganKnow healing ointment and a loose bandage. OreganKnow has been shown in University tests to speed healing, prevent infections and results in better appearing post healing scars. It will not cause allergic contact dermatitis as seen with many OTC healing ointments and antibacterial ointments such as triple antibiotic ointment. Blister essential oil therapy is often sought but occasionally leads to secondary allergic contact dermatitis. The water soluble Oregano extract in OreganKnow healing ointment has the essential or volatile oil removed but retains Oreganos anti-inflammatory, anti oxidant and anti microbial healing natural chemicals.
Pain often accompanies a friction bullae and blister relief includes proper wound care as outlined above plus an oral analgesic such as Tylenol or ibuprofen. Also be vigilant for the early development of an infection. If the area of blister develops surrounding red, swelling, pus or increased pain than seek medical attention as you may need an oral antibiotic.
Cold or fever sores most commonly seen on the lip and fever blister treatment is done in similar manner to standard blister care. Occasionally cold sores need prescribed topical, Many people search online for oral antiviral therapy lip blister remedies but forget that these lesions are highly contagious to others, even when there are no skin lesions. This should be discussed with your doctor. Herpes lip blister treatment should also start with prevention which includes lip balm sunscreens. Herpes blisters are particularly contagious and dangerous to those with weakened immune systems such as people on immunosuppressant medications, chemotherapy or those infected with HIV.
A toe blister is usually secondary to friction but may be an early indicator of a serious problem such as nerve damage due to diabetes. Known as diabetic neuropathy, this results from sensory loss in the feet and resultant undetected, painless, continuous pressure. While foot blister treatment is similar to that described above, these diabetic foot blister and resultant ulcers need medical attention. Of particular importance is optimal diabetic control and removal of dead tissue through a process called debridement performed by a podiatrist or surgeon. Local pressure reduction on the ulcer prone areas is also essential as is control of infections.
