Should I go to the ER or my primary care doctor?

ER for: chest pain, sudden severe headache, difficulty breathing, stroke symptoms (face drooping, arm weakness, speech difficulty), heavy bleeding, or high fever with confusion. Primary care for: persistent but non-emergency symptoms like fatigue, weight loss, chronic pain, or gradual changes. Urgent care fills the middle ground — infections, minor injuries, moderate symptoms that can't wait for a PCP appointment.

How do I know if I'm being a hypochondriac?

Seeking evaluation for concerning symptoms isn't hypochondria — it's responsible health behavior. Health anxiety becomes problematic when it's constant, disproportionate to symptoms, and persists despite medical reassurance. If you're worried about one specific symptom, getting it checked is reasonable. If you're constantly worried about multiple potential diseases, that pattern itself may benefit from treatment.

What screenings should I be getting regularly?

For average-risk adults: blood pressure annually, cholesterol every 4-6 years (starting at 20), diabetes screening (at 35 or earlier with risk factors), colorectal cancer screening (at 45), mammograms (at 40), cervical cancer screening (21-65), and lung cancer screening (50-80 with significant smoking history). Your primary care doctor can personalize this based on your risk factors.

When to See a Doctor: 10 Warning Signs You Shouldn't Ignore

We've all been there: something feels off, and you're trying to decide between "it's probably nothing" and "should I call the doctor?" Most of the time, symptoms resolve on their own. But certain signs indicate something that needs professional evaluation — and waiting can mean the difference between a simple treatment and a serious complication. Here are 10 warning signs that merit a call to your doctor or, in some cases, an emergency room visit.

1. Sudden, Severe Headache

A "thunderclap headache" — the worst headache of your life, reaching maximum intensity within seconds to minutes — is a medical emergency. It could indicate a subarachnoid hemorrhage (brain bleed), which is fatal in about 50% of cases without treatment. This is different from a migraine building gradually. If you experience sudden, explosive head pain, call 911.

Also concerning: headaches that are progressively worsening over days/weeks, headaches with fever and stiff neck (possible meningitis), or headaches with vision changes, confusion, or weakness on one side of the body (possible stroke).

2. Unexplained Weight Loss

Losing more than 5% of your body weight over 6-12 months without trying is a red flag. For a 160-lb person, that's 8+ pounds. Potential causes range from thyroid disorders (treatable) to depression to diabetes to cancer. It's not always serious, but unintentional weight loss always deserves investigation — starting with blood work and a thorough history.

3. Chest Pain or Pressure

Not all chest pain is a heart attack, but you shouldn't try to diagnose yourself. Seek emergency care for: pressure, squeezing, or heaviness in the chest; pain radiating to the arm, jaw, neck, or back; chest symptoms with shortness of breath, sweating, nausea, or lightheadedness. Women and diabetic patients are more likely to have "atypical" presentations — fatigue, nausea, back pain, or jaw pain without classic chest pressure. When in doubt, call 911. It's better to have a false alarm than a missed heart attack.

4. Shortness of Breath That's New or Worsening

Sudden shortness of breath at rest is an emergency — it could indicate pulmonary embolism (blood clot in the lung), heart failure, pneumonia, or severe asthma attack. Gradual worsening over weeks could indicate heart failure, COPD progression, anemia, or pleural effusion. If you can't complete a sentence without gasping, that's urgent.

5. Changes in Bowel or Bladder Habits

Persistent changes lasting more than 2-3 weeks warrant evaluation:

Blood in stool (red or black/tarry) — could indicate colorectal cancer, ulcers, or hemorrhoids. Never assume it's hemorrhoids without evaluation, especially after 45.
Blood in urine — may indicate bladder or kidney cancer, infection, or kidney stones
Persistent diarrhea or constipation — new pattern lasting weeks
Narrowing of stool — could indicate a mass in the colon

A colonoscopy is the gold standard for evaluating persistent lower GI symptoms in adults.

6. Persistent Fever

A fever above 103°F (39.4°C) in adults warrants medical attention. A lower-grade fever that persists for more than 3 days, or fever with no obvious cause (no cold/flu symptoms), should be evaluated. Fever can indicate infection (including hidden ones like endocarditis or abscess), autoimmune disease, or in rare cases, malignancy. Fever with rash, stiff neck, or confusion is an emergency.

7. Sudden Vision Changes

Sudden loss of vision in one eye, sudden double vision, or a sudden increase in floaters with flashes of light require same-day evaluation. These can indicate retinal detachment (floaters + flashes), stroke or TIA (vision loss, double vision), or acute glaucoma (eye pain with vision changes and halos around lights). Time matters — retinal detachment treated within 24 hours has much better outcomes than delayed treatment.

8. A Wound That Won't Heal

A sore or wound that doesn't heal within 3-4 weeks — especially on sun-exposed skin — needs examination. Non-healing wounds can indicate skin cancer (particularly basal cell carcinoma), diabetes-related healing impairment, or vascular insufficiency. Non-healing mouth sores lasting more than 2 weeks should be evaluated for oral cancer, especially in tobacco or alcohol users.

9. Persistent Fatigue

Everyone gets tired. But fatigue that's severe, persistent (lasting more than 2-3 weeks), and not explained by poor sleep or overwork could indicate anemia, thyroid dysfunction, diabetes, heart failure, depression, sleep apnea, or other conditions. If rest doesn't restore you, something is driving the fatigue — and it's usually identifiable and treatable with appropriate testing.

10. New or Changing Moles

Use the ABCDE rule for evaluating moles:

Asymmetry — one half doesn't match the other
Border — irregular, ragged, or blurred edges
Color — uneven, with shades of brown, black, red, white, or blue
Diameter — larger than 6mm (pencil eraser), though melanomas can be smaller
Evolving — changing in size, shape, or color

Any mole that meets one or more of these criteria should be examined by a dermatologist. Melanoma caught early (stage I) has a 99% five-year survival rate; caught late (stage IV), it drops to 32%. Early detection is everything.

The General Rule

When in doubt, err on the side of being evaluated. Doctors would much rather see you for a false alarm than see you too late for a real problem. The "it's probably nothing" instinct is correct most of the time — but the consequences of the times it's wrong can be severe. Trust your instinct when something feels genuinely different from your normal. You know your body better than anyone.
