When to Seek Emergency Care for Lymphoma
I'm glad you're thinking ahead about when your loved one needs urgent care. Here are the key warning signs that warrant an immediate trip to the emergency room:
SEEK EMERGENCY CARE IF:
Breathing or Chest Problems
- Difficulty breathing or shortness of breath at rest
- Chest pain or pressure
- Severe coughing
- Wheezing or stridor (high-pitched breathing sounds)
Why this matters: Lymphoma can affect the chest area (mediastinum) or cause fluid buildup around the lungs, which requires immediate evaluation.
Severe Infections or Fever
- Fever above 103°F (39.4°C) with chills
- Fever combined with severe weakness, confusion, or difficulty staying alert
- Signs of infection (severe sore throat, difficulty swallowing, severe cough)
Why this matters: Lymphoma and its treatments can weaken the immune system, making infections life-threatening.
Neurological Symptoms
- Severe headache with fever or stiff neck
- Confusion or difficulty thinking clearly
- Seizures
- Severe dizziness or loss of balance
- Weakness or numbness on one side of the body
Why this matters: Lymphoma can occasionally affect the nervous system or brain.
Severe Bleeding
- Vomiting blood or coughing up blood
- Severe nosebleeds that won't stop
- Blood in stool (black or bright red)
- Unexplained severe bruising
Why this matters: Lymphoma can affect blood cell counts, and some treatments impact clotting.
Severe Abdominal Pain
- Sudden, severe belly pain
- Abdominal pain with vomiting
- Inability to keep down food or liquids for several hours
Why this matters: Lymphoma can affect organs in the abdomen.
Severe Allergic Reaction
- Difficulty breathing
- Swelling of face, lips, or throat
- Severe rash or hives
- This is especially important if occurring during or shortly after treatment
CALL YOUR ONCOLOGY TEAM FIRST IF:
- You have a fever (any temperature above 100.4°F/38°C) and are undergoing active treatment
- Severe pain that's new or different from usual
- Persistent vomiting or inability to take medications
- Unusual bleeding or bruising
- Severe fatigue or weakness
Your oncology team may advise you to go to the ER or may have specific instructions for your situation.
IMPORTANT CONTEXT:
According to the NCCN Guidelines for Patients with Lymphoma, supportive care is a critical part of treatment. Your care team should provide you with specific emergency contact information and guidance tailored to your particular type of lymphoma and treatment plan.
Keep this information handy:
- Your oncologist's emergency contact number
- Your hospital's emergency department number
- A list of current medications and treatments
- Your lymphoma diagnosis and stage (if known)
This information is for educational purposes only. Always consult your healthcare team for personalized medical advice and decisions.
