Athlete’s Foot

Posted on February 15, 2026 by Patrick Hercules

Athlete’s foot, also known as tinea pedis, is a skin infection caused by dermatophytes, which are the same fungi that cause jock itch and ringworm. However, unlike jock itch and ringworm, athlete’s foot can often come back.

The fungi that cause athlete’s foot thrive in warm, damp places, which can occur when feet get hot and sweaty inside closed shoes, creating sweaty socks. They can also live on wet towels.

The fungi that cause athlete’s foot can spread easily to other people because they can travel on hands, towels, and other surfaces. A person can get athlete’s foot through contact with someone who has it and by touching surfaces where fungi are present. It can also spread from the feet to other parts of the body and may happen when a person uses a towel to dry their feet and then uses the same towel to dry the rest of their body, such as the groin area, which causes jock itch.

Athlete’s foot can affect one or both feet, usually starting between the toes. It causes common symptoms that include:

Dry, scaly skin on the bottom and sides of the feet

Itchy skin, occurring especially right after taking off shoes and socks

Swollen skin that may look red, purple, or gray, depending on skin color

A burning or stinging sensation

Blisters

Scaly, peeling, or cracked skin between the toes

A person has a higher risk of developing athlete’s foot if they:

Sweat a lot

Often wear closed shoes

Walk barefoot in public showers, pools, or locker rooms

Share towels, shoes, rugs, or bed linens with someone who has athlete’s foot

Athlete’s foot can cause complications for people with weakened immune systems, such as those with diabetes, leading to a bacterial skin infection called cellulitis.

A healthcare provider may be able to diagnose athlete’s foot after an examination. Some types of athlete’s foot can look similar to dry skin or dermatitis. To help rule out other conditions, your provider may take a small skin sample of the affected area for lab testing.

Treatment for athlete’s foot may involve self-care and over-the-counter products such as antifungal cream, spray, or powder. If these over-the-counter products do not work, a healthcare provider may prescribe a stronger antifungal medicine to apply to the affected area.

Several tips can help ease the symptoms of athlete’s foot and lower the risk of it coming back. They include:

Keeping your feet clean and dry

Wearing different shoes every day

Changing socks regularly

Wearing breathable and lightweight footwear

Using an antifungal product

Wearing waterproof shoes or sandals around public pools, showers, and locker rooms

Not scratching the rash in the affected area

Not sharing shoes

Hidradenitis Suppurativa

Posted on January 15, 2026 by Patrick Hercules

Hidradenitis suppurativa, also known as acne inversa, is a condition that causes small, painful lumps to form underneath the skin. These lumps usually develop in areas such as the armpits, the groin, buttocks, and breasts where the skin rubs together.

Hidradenitis suppurativa starts after puberty and usually before the age of 40. It can last for many years, worsening over time.

Hidradenitis suppurativa can affect one or more areas of the body, with several signs and symptoms, including:

Blackheads- small, pitted areas of the skin that often appear in pairs

Painful pea-sized lumps that form under the skin in areas where more sweat and oil glands are present, or where the skin rubs together, that can last for weeks or months

Leaking bumps or sores that can get bigger, break open, and drain pus with an odor

Tunnels that form under the skin. These tunnels connect lumps and heal slowly, and drain blood and pus

Some people who have hidradenitis suppurative experience only mild symptoms; however, the course of the disease varies extremely. Excess weight and smoking are associated with worse symptoms, but people who are thin and smoke can also experience severe symptoms of the disease.

Hidradenitis suppurativa occurs when hair follicles become blocked. The cause of the blockage isn’t known; however, experts think it may be connected to hormones, genetic predisposition, cigarette smoking, or excess weight.

Several risk factors can increase the chance of developing hidradenitis suppurativa. They include:

Race

Family history

Certain conditions

Smoking

Severe and persistent hidradenitis can cause complications, including:

Infection in the affected area

Restricted movement due to sores and scar tissue

Skin cancer, such as squamous cell carcinoma, has been reported with long-term hidradenitis suppurativa

Scars and skin changes after wounds have healed, leaving pitted skin and rope-like scars

Swelling in the arms, legs, or genital area, due to scar tissue caused by hidradenitis that blocks the lymph nodes in those areas from draining

Psychological effects and social isolation, such as depression, anxiety, or not wanting to go out in public due to the location, drainage, and odor of the sores

Lifelong pain

Hidradenitis suppurativa can often be mistaken for acne or pimples. A healthcare provider can make a diagnosis based on signs and symptoms, skin appearance, and medical history. Hidradenitis suppurativa can be difficult to diagnose and requires specialized care, so a healthcare provider may refer a patient to a dermatologist.

There aren’t any laboratory tests available to diagnose hidradenitis suppurativa; however, if there is pus or drainage present in the wounds, samples may be taken for testing.

Treatment for hidradenitis suppurativa can include medications, surgeries, or both to help control symptoms and prevent complications of the condition.

Medications used to treat hidradenitis suppurativa can include:

Antibiotics

Steroid injections

Hormonal therapy

Biologics

Retinoids

Pain medicine

Surgical procedures used to treat hidradenitis suppurativa include:

Uncovering the tunnels under the skin by removing tissue to expose them

Punch debridement, which removes a single inflamed bump

Laser therapy

Surgical removal of all the infected skin

Home Remedy to Rid Blackheads

Posted on February 22, 2016 by Zakiya Hazel-Jemmott

Blackheads are most common on your face, specifically on your nose and the sides of your nose. Common and annoying, blackheads occur when your pores become clogged with excess sebum (an oil created by the sebaceous glands that keeps skin supple) and dead skin cells. The difference between a black head and a white head is simply whether or not the pore is open or closed. Blackheads aren’t as unpleasant as pimples but they are still a nuisance to have. Here are some home remedies to curing pesky blackheads using items you might already have in your kitchen.

A little baking soda goes a long way for blackheads, but don’t overdo it, as it can seriously dry out your skin thanks to its saltiness. While pH may or may not have a role to play in blackheads, the biggest reason baking soda helps is because of it’s small, fine, granules that can work as a natural and inexpensive way to occasionally exfoliate and remove anything clogging your pores (and therefore causing blackheads.)

You will need baking soda and fresh water.

Mix the water with enough baking soda to form a thick, but spreadable, paste. Using a gentle circular motion, massage the paste into your skin. Rinse thoroughly with plain water, pat your face dry, and then make sure you moisturize.

Since blackheads are caused by open, clogged, pores reacting to oxygen, it only makes sense that “shrinking” your pores down will help. Lemon juice is just the astringent substance needed to get the job done, however, it can lighten skin temporarily and it does make you sensitive to the sun, so load up on sunscreen if you plan on using this method in the summertime. If you have sensitive skin, try diluting the lemon juice with water first.

You will need a lemon, cotton balls and a small bottle.

Rinse your face and pat dry. Squeeze the lemon juice into a small bottle and then use just enough to dampen a cotton ball. Apply to affected areas 3-4 times a week, at bedtime. When you wake up, rinse your face with luke-warm water and apply moisturizer as usual. Store the rest of the juice in the refrigerator for up to a week. Be aware-the juice can sting sometimes!

Green tea can also be used to treat blackheads. Mix one teaspoon of dry green tea leaves with a little water to make a paste. Then, gently scrub the paste over the affected area for two to three minutes. Rinse your face with lukewarm water and apply a little bit of moisturizer once your face is dry. This scrub deep cleans oily skin and helps unclog pores.

There are many prescription medicines for the treatment of blackheads if trying natural treatments isn’t your thing. To make an appointment at Jamaica Hospital’s Dermatology Department please call, 718-206-6742.

Vitiligo: Causes, Myths, and Facts

Posted on January 25, 2016 by Zakiya Hazel-Jemmott

Vitiligo (vit-uh-lie-go) also called ‘leucoderma’ is a condition in which there is a development of milky-white patches on the skin. Anyone can get this skin disorder. Millions of people of all races and ethnicities worldwide have Vitiligo. It occurs in 0.5-2% of the general population. Some well-known cases of vitiligo have occurred in celebrities such as Michael Jackson, supermodel Winnie Harlow, and comedian Steve Martin.

So what causes vitiligo? Vitiligo is usually seen on the skin but other areas such as the scalp, lips and genitals can also be affected. Patches of hair can turn white. It develops because color producing cells in our skin called melanocytes, die.

Scientists have not completely understood why these cells die. Multiple factors such as genetics, a weak immune system which attacks its own cells, and increased free radical-induced damage (oxidative stress) may be the cause. Those whose parents have vitiligo and associated autoimmune diseases are more likely to get it as compared to the general population, although in most cases there is no family history of the condition. Certain factors such as skin injury and severe sunburn can cause development of new patches in a predisposed individual as well.

There are several myths associated with the spread of vitiligo but the fact is that vitiligo is not contagious. People also think that it is caused by eating white foods and drinking too much milk which is also false. Certain prescribed medications can stop the spread of new vitiligo spots but is not guaranteed, as new spots may appear but recover as treatment proceeds. Although vitiligo is not life-threatening it is life-changing. Those afflicted with vitiligo and their families face social stigmatisation leading to low self-esteem, anxiety, embarrassment, anger and even serious depression.
