When to worry about unexplained fever if you have lymphoma

Fever can occur with lymphoma, but it may also signal an infection, a reaction to treatment, or another illness. Your care team considers the fever alongside swollen glands, night sweats, cough, urinary symptoms, skin changes, recent procedures, and blood results. The symptom alone cannot identify the cause.

Write down the start time, readings, chills, and medicines taken. Mention recent chemotherapy, immunotherapy, steroids, a biopsy, a central line, or contact with someone who is unwell.

Follow the fever instructions from your lymphoma team and call the contact they provided. Share your current treatment, medicines, temperature readings, and any new symptoms. Do not change cancer treatment or start leftover antibiotics on your own. Ask whether you should attend a clinic, emergency department, or another service for examination and blood tests.

Get urgent help for fever with breathing difficulty, chest pain, confusion, collapse, severe drowsiness, repeated vomiting, inability to drink, or a rapidly spreading rash. Shaking chills, a painful catheter site, or feeling suddenly much worse also require immediate advice. Tell clinicians that you have lymphoma and give them your treatment details.

Ask what readings require a call, which symptoms mean emergency care, how often to recheck your temperature, and whether you should avoid particular medicines before assessment. Clarify the out-of-hours number and what to do if the fever returns.
