When a new health concern pops up, figuring out where to seek care may feel overwhelming. Do you start with the primary care physician you see for annual exams? Or should you consult a specialist with expertise in a particular area? Or is the issue so urgent that you should head straight to the emergency room?

Read on for a quick guide to help you determine which healthcare provider you may want to see in different situations.

What your primary care provider can help with

Think of your primary care provider as your main care provider in non-emergency situations. They can:

Provide preventive care and conduct annual physicals
Advise you on lifestyle choices that can lead to healthy habits
Identify and treat common medical conditions
Assess the urgency of a medical problem and direct you to the appropriate place for care
Give you referrals to a medical or surgical specialist if needed
Help you stay up to date on vaccinations you may be due for
Write you a prescription for things like physical therapy
Help you navigate new or unexplained symptoms like digestive changes, joint pain, sleep problems, headaches, fatigue or a fever
Order routine testing, such as a mammogram or colonoscopy

“Primary care is like being the quarterback in medicine,” says Robert Thompson, DO, MS, CPE, FAAFP, a board-certified family medicine physician and medical contributor for Care Point Boston. “We look at the whole field (the total picture) that includes symptoms, currently prescribed medications, family history and how one condition may be affecting another.”

When to see a specialist

Specialists are doctors who have additional training and expertise in a particular area of medicine. Examples of specialists can include:

Cardiologist: Specializes in conditions affecting the heart and blood vessels.
Neurologist: Specializes in conditions involving the brain and nervous system.
Oncologist: A doctor whose main specialty is diagnosing and treating cancer
Ophthalmologists: Specialize in comprehensive eye and vision care
Hematologists: Specialize in blood disorders and diseases
Dermatologists: Care for skin, hair and nails
Endocrinologists: Manage conditions involving hormones and the endocrine system, including diabetes
Gastroenterologists: Treat conditions affecting the digestive system
Pulmonologists: Physicians who focus on lungs and breathing conditions
Rheumatologists: Treat rheumatic diseases, including certain types of arthritis and autoimmune conditions

“Specialist care is especially important when the diagnosis has already been made and specific treatment for this diagnosis is needed, symptoms continue and worsen despite initial treatment, test results show abnormalities or when the diagnosed condition falls outside of the scope of the primary doctor,” says Thompson.

Your doctor will often refer you to a specialist if your care reaches the point where you can benefit from seeing one. For instance, if you develop persistent joint pain that doesn’t resolve after your primary care provider’s recommended treatment, then you may want to see a rheumatologist for further evaluation. Or if you have a mole on your body that is changing color, it might be a good idea to have it checked out by a doctor with an expertise skin health, aka a dermatologist.

“If they’ve completed a full course of treatment, medication, physical therapy or whatever their primary doctor prescribed, and the symptom still hasn't improved after the expected timeframe, that can be a reason to consider specialty care,” says Raymond Douglas, MD, PhD, a board-certified aesthetic and reconstructive oculoplastic surgeon in Beverly Hills, California.

The same mentality can apply to situations where a problem improves with treatment but repeatedly comes back. Douglas also recommends paying attention to symptoms that change, spread or are joined by new symptoms — “like pain that starts in one joint and moves to others or fatigue that adds new symptoms like weight change or hair loss. It can be because the underlying issue is broader than the original diagnosis accounted for,” he explains.

You can also see a specialist if you are seeking a second opinion about a diagnosis you received from your primary care provider.

Do you need a referral to see a specialist?

Some insurances may require a referral from your primary care physician before being seen by a specialist. This often comes down to your insurance plan and how it operates. Before scheduling an appointment yourself, check your insurance plan to see whether you need a referral and whether the specialist is in your network. You can also call the specialist’s office and ask whether they accept your insurance and require a referral. And even when a referral isn't required, your primary care doctor may be able to recommend the appropriate type of specialist based on your symptoms and medical history, so it’s a good idea to check in with them.

Keep your primary care physician in the loop

Even if you see a specialist, it’s a good idea to have your records from those appointments transferred over to your primary care physician so they can stay up to date on any new diagnoses or treatment plans. Coordinating care can become particularly important as you get older, especially if you're managing multiple health conditions, medications or specialists. This can help your primary care physician look at your health as a whole and keep tabs on things like any prescriptions you may be taking.

“Having many doctors is no guarantee that you will receive better care; the ultimate goal is to make certain that someone is putting the puzzle pieces together,” says Thompson.

When urgent care may be an option

If you have a health concern you would normally bring to your primary care provider but can’t get an appointment soon enough, you could consider going to urgent care. They can help to field new symptoms like a cough or fever, or they can check if something like a stubbed toe is actually broken by doing an in-clinic X-ray.

Urgent care can help with:

Everyday illnesses and symptoms, such as cold or flu symptoms, a sore throat, ear pain, a migraine, a mild fever or a small rash
Non-emergency injuries, including a sprain, minor back pain, a small cut or burn, certain minor fractures or a minor eye injury

If you go to urgent care and receive a diagnosis, it’s a good idea to follow up with your primary care physician. This is important because they know your medical history and can help manage chronic conditions and preventive care over time. Urgent care is also not a replacement for emergency care when symptoms are severe or potentially life-threatening.

If you are experiencing new symptoms that come on suddenly, are severe, or are potentially life-threatening, don't wait for an appointment with either your PCP or a specialist. Seek emergency medical care by dialing 9-1-1 or heading to your local emergency room. Symptoms that warrant this type of emergency response include:

Choking or difficulty breathing
Severe head injuries, especially those involving passing out or confusion
Serious neck or spine injuries
Severe burns or electric shock
Intense chest pain or pressure
A seizure that lasts more than 60 seconds or you don’t quickly recover from
Suddenly being unable to see, speak, walk or move
Sudden weakness or drooping on one side of the body
Passing out or fainting
Severe or uncontrollable bleeding
Inhalation of smoke or poisonous fumes
A severe allergic reaction
A high fever accompanied by a headache and/or stiff neck
Persistent vomiting or diarrhea, especially if accompanied by signs of severe dehydration
