A blister is a fluid filled lesion; and may develop on the knuckles due to a host of reasons. It is a tiny pocket of fluid in the upper layers of the skin, characteristically occurring due to burning, friction, freezing, chemical exposure or infection.
By and large, a blister is filled with a clear fluid known as plasma or serum.
What Causes Blisters On Knuckles?
A blister develops when your skin has been damaged due to friction, cold, heat or chemical exposure. Fluid builds up in between the epidermis and the layers of the skin below. This fluid cushions the tissue beneath, and protects it from more damage and expedites healing.
The following are the common etiological factors for blisters to develop on the knuckles:
- Atopic dermatitis
- Contact dermatitis, due to allergy to a cloth or jewelry
- Xerotic eczema
- Friction related blisters
- Exposure to certain chemicals
- Exposure to extreme cold
- Diabetes mellitus
- Chronic kidney failure
- Obstructive biliary disorder
- Cholestasis disorder during pregnancy
- Senile pruritus
Natural Ways To Treat Blisters On Knuckles
Blisters on the knuckles need not be a cause of major worry; however, you must not neglect them.
Only your doctor can advise you which treatment regimen is appropriate for your particular medical situation. It is very essential that you debate over all treatment options with your health care provider before you take a decision, including whether to commence or suspend a treatment plan.
- You must protect the blister from abrasion or friction and you should ensure that the blister stays intact. In case there is a breach in the skin, the tissue is then more susceptible to infection.
- Blisters do get infected. It is vital that you prevent infection with good hygiene practices, and treat adequately with anti-biotic if necessary. There is intensified worry about MRSA and other infections from blisters, thus, they must be watched cautiously.
- Experts recommend calamine lotion to soothe the pain and discomfort; they ease discomfort in the case of burns.
- Tea tree essential oil is also helpful to keep the blister clean and to ward off against infection. Add 2 to 3 drops of tea tree essential oil to a bowl of hot water. Dip a swab of cotton and clean the area thoroughly. Repeat 4 to 5 times daily for a couple of days.
- Place your knuckles in cold water for a few minutes, frequently through the day. Avoid ice since it could further damage your skin.
- You may successfully drain a disinfected blister with a similarly disinfected pin with a puncture or two and air dry. You could use alcohol to disinfect the blister as well as the pin. Gradually expose the pinhole and the whole blister area to alcohol over the next few days when the sensitivity has reduced and an exposure to water and soap results in no discomfort.
- You must put on protective gloves when you handle cleaning products, detergents, solvents and other chemical substances.
- Garlic is an excellent home remedy to manage blistering and to preventing infections too. Have 3 flakes of garlic daily till the blisters subside.
