How to Use This Symptom Checker
Our symptom checker helps you understand potential causes of your symptoms and decide whether you need immediate care, a doctor's appointment, or can safely try self-care at home. Here's how to get the most accurate information:
1. Be specific: Describe exactly what you're feeling — is the pain sharp, dull, burning, or throbbing? Where exactly is it located?
2. Include timing: When did it start? Is it constant or does it come and go? What time of day is it worst?
3. Note severity: Rate your symptom on a 1-10 scale. Is it interfering with daily activities?
4. Mention context: Any recent injuries, illnesses, new medications, or life changes? Have you had this before?

|---|---|---|
| 🚨 Emergency (911/ER) | Immediately | Chest pain, stroke symptoms, severe bleeding, difficulty breathing, loss of consciousness |
| ⚠️ Urgent Care | Same day | High fever, moderate injuries, UTI symptoms, ear pain, persistent vomiting |
| 📅 Doctor Appointment | Within 1-2 weeks | Ongoing symptoms, medication questions, new rash without fever, chronic condition management |
| 🏠 Self-Care at Home | Monitor 24-72 hours | Mild cold symptoms, minor headache, mild muscle soreness, minor cuts/bruises |
When in doubt, err on the side of caution. A telehealth visit can help determine if you need in-person care.
Symptoms That Always Need Medical Attention
Certain symptoms — regardless of how you feel otherwise — warrant prompt medical evaluation. These "red flag" symptoms may indicate serious conditions that benefit from early treatment:
- Unexplained weight loss — losing 10+ pounds without trying over 6-12 months
- Blood where it shouldn't be — in urine, stool, vomit, or coughed up
- Persistent fever — over 103°F (39.4°C) or lasting more than 3 days
- Severe or sudden onset symptoms — "worst ever" headache, sudden vision loss, sudden weakness
- Symptoms that wake you from sleep — especially pain or shortness of breath
- Progressive worsening — symptoms steadily getting worse over hours or days
- New symptoms with chronic conditions — diabetics with new wounds, heart patients with new chest symptoms
- Changes in consciousness or confusion — especially in elderly or after head injury
What to Do While Monitoring Symptoms
For mild symptoms that don't require immediate medical attention, these general self-care strategies can help while you monitor your condition:
💡 The RICE Method for Injuries
Rest the injured area. Ice for 20 minutes every 2-3 hours. Compress with elastic bandage. Elevate above heart level when possible. Effective for sprains, strains, and minor injuries in the first 48-72 hours.
Stay hydrated: Drink plenty of water, especially with fever, vomiting, or diarrhea. Clear broths and electrolyte drinks can help replace lost minerals.
Rest appropriately: Your body heals during rest. Don't push through significant symptoms — it often prolongs recovery.
Track your symptoms: Note timing, severity, and what makes symptoms better or worse. This information is valuable if you do need to see a doctor.
Use OTC medications wisely: Follow package directions. Acetaminophen for fever/pain, ibuprofen for inflammation, antihistamines for allergies. Don't exceed recommended doses.
Limitations of Symptom Checkers
While symptom checkers are useful educational tools, they have important limitations you should understand:
- Cannot examine you: Physical examination, vital signs, and diagnostic tests are essential for accurate diagnosis
- Cannot account for everything: Your full medical history, medications, and unique circumstances matter
- May not catch rare conditions: Symptom checkers tend to focus on common causes
- Cannot replace clinical judgment: Healthcare providers are trained to recognize subtle patterns and red flags
- Provide possibilities, not diagnoses: Many different conditions can cause similar symptoms
Bottom line: Use this tool to become a better-informed patient, not to avoid medical care when you need it. Trust your instincts — if something feels seriously wrong, seek professional evaluation.
