Acne

Acne is a skin condition in which clogged hair follicles lead to pimples and other spots. It often affects the face, chest, shoulders, or back. Acne is common in younger people, but adults can have it too.

Mental health

Aging & caregiver support

Caregiver support focuses on people helping someone with daily needs because of illness, disability, injury, or aging. That role can be rewarding and demanding. The caregiver's own physical health, emotions, and need for help matter too.

Urgent care

Allergies

An allergy happens when the immune system reacts to a substance that is harmless to many other people. Triggers can include pollen, dust, foods, medicines, and insect stings, with reactions that range in severity.

Mental health

Anxiety

Anxiety can be a normal response to uncertainty. Anxiety disorders involve fear or worry that persists, may occur across different situations, and can interfere with work, relationships, or ordinary activities. There are several distinct types.

Urgent care

Birth control

Birth control, also called contraception, is a care topic about preventing pregnancy. Options include barrier methods, medicines, devices, and procedures. The right conversation depends on health history, preferences, and future pregnancy plans.

Dermatology

Boils

A boil is a skin infection involving a hair follicle and nearby tissue. It may begin as a tender, swollen bump and become painful as pus collects. Some people have one boil; others experience recurring episodes.

Urgent care

Cold & flu

Colds and flu are respiratory infections caused by different viruses. They can share symptoms such as cough, sore throat, and congestion. Flu may also bring fever and body aches, and symptoms can overlap with COVID-19.

Dermatology

Cold sores

Cold sores are painful blisters usually found on or near the lips. They are caused by herpes simplex virus, most often HSV-1. They can return after an earlier infection and are different from canker sores inside the mouth.

Urgent care

Cough

A cough is a reflex that helps clear the throat and airways. It may accompany a short respiratory illness or persist for other reasons, including asthma, allergies, irritation, reflux, or certain medicines.

Urgent care

COVID-19

COVID-19 is an infection caused by the SARS-CoV-2 virus. It spreads through respiratory particles and can affect people differently. Its symptoms overlap with other respiratory illnesses, so the illness cannot be identified from symptoms alone.

Mental health

Depression

Depression is a mental health condition that can affect emotions, thinking, and daily activities. It is more than a passing low mood and may change sleep, eating, work, or the ability to manage ordinary responsibilities.

Dermatology

Dermatitis

Dermatitis is a term for skin inflammation. Contact dermatitis develops after exposure to an irritating substance or an allergen. Other forms, including atopic dermatitis, have different contributing factors, so understanding the type is important.

Urgent care

Diarrhea means loose, watery bowel movements that happen more often than usual. It can be brief or ongoing. Infections, medicines, food sensitivities, and conditions affecting digestion are among its possible causes.

Urgent care

Ear pain

Ear pain is discomfort in one or both ears. It can arise from an ear problem or be felt there because of pain in the jaw, teeth, or throat. An earache does not automatically mean an infection.

Dermatology

Urgent care

Erectile dysfunction

Mental health

Grief & loss

Grief is a natural response to a significant loss. After a death, the period of mourning is also called bereavement. Grief can affect emotions, thoughts, sleep, appetite, relationships, and the way everyday life feels.

Urgent care

Hair loss

Hair loss means more thinning or shedding than expected, sometimes in a particular pattern or area. Family history, aging, health conditions, medicines, stress, and nutrition can contribute, so understanding the cause matters.

Urgent care

Headache

A headache is pain involving the head. Tension headaches, migraine, and cluster headaches are different examples. The timing, location, associated symptoms, and changes from a person's usual pattern help a clinician understand it.

Primary care

High blood pressure

High blood pressure, also called hypertension, means the force of blood against artery walls stays higher than it should. It often causes no noticeable symptoms, making measurement and a clinician's interpretation important.

Primary care

High cholesterol

Cholesterol is a substance the body needs, but too much of certain types in the blood can contribute to plaque in arteries. A cholesterol discussion considers test results alongside overall heart and blood-vessel risk.

Dermatology

Hives

Hives are raised, often itchy areas of swollen skin, also called urticaria. They may follow an allergic reaction, but infections, stress, or other triggers can also contribute. The appearance alone does not identify the cause.

Urgent care

Insect bites & stings

Insect bites and stings can cause discomfort where they occur. Some mainly itch, while others hurt. Reactions vary, and certain insects can transmit infections or trigger a serious allergic reaction in susceptible people.

Dermatology

Keratosis

Keratosis appears in the names of different skin growths or changes. Seborrheic keratoses are benign growths; actinic keratoses are precancerous changes. Some spots can look similar, so the full name and a professional examination matter.

Mental health

LGBTQ+ support

LGBTQ+ support means space to discuss wellbeing with respect for sexual orientation, gender identity, and personal experience. Conversations may focus on connection, relationships, community, or finding welcoming resources. LGBTQ+ identity is not a diagnosis.

Mental health

Life changes

A medication refill is an additional supply of a medicine already prescribed. It is a care and pharmacy topic, not a diagnosis. The prescriber and pharmacy may need to review the prescription and current information.

Dermatology

Mental health

The sinuses are air-filled spaces around the nose. Sinusitis means their lining is inflamed. Swelling can interfere with mucus drainage and contribute to discomfort, with infections, allergies, and nasal problems among the possible contributors.

Dermatology

A skin cyst is a closed sac beneath the skin. One common type, an epidermoid cyst, contains dead skin cells and often grows slowly. A lump may become tender, warm, or swollen if it becomes inflamed or infected.

Dermatology

Pigmentation describes skin coloring, much of which comes from melanin. Changes in melanin production can make areas darker or lighter. Many conditions and exposures can affect pigmentation, and changes may involve small patches or larger areas.

Urgent care

Sleep issues

Sleep issues include difficulty falling asleep, staying asleep, or getting restorative sleep. Different sleep disorders can affect breathing, movement, timing, or wakefulness. Both the amount and quality of sleep matter for everyday functioning.

Urgent care

Sore throat

A sore throat is discomfort or irritation in the throat. Respiratory viruses are common causes, but allergies, smoke, and bacterial infections can also contribute. The cause helps determine what evaluation and care are appropriate.

Mental health

Stress management

Stress management means understanding how demands or challenges affect you and finding ways to respond. Stress can involve both body and mind. The most useful approach depends on the causes, your routines, and the support available.

Mental health

Substance use & addiction

Substance use concerns involve alcohol, drugs, or medicines used in ways that may cause harm. A substance use disorder can affect control over use and everyday life. Addiction is a health condition, not a character flaw.

Primary care

Thyroid conditions

The thyroid is a gland in the neck that makes hormones affecting how the body uses energy. Thyroid conditions include too much or too little hormone production, inflammation, nodules, and other changes requiring evaluation.

Mental health

Trauma & PTSD

People can have many reactions after experiencing or witnessing a traumatic event. Post-traumatic stress disorder may develop when ongoing symptoms interfere with everyday life. Trauma reactions can affect emotions, sleep, concentration, and a person's sense of safety.

Primary care

Primary care

Urgent care

Yeast infections

Yeast infections occur when a fungus such as Candida grows enough to cause a problem. They can affect different areas, including the mouth, skin, and vagina, with symptoms that depend on the affected site.
