Be seen today
If you are receiving chemotherapy, contact your cancer team immediately about a fever, shaking chills, or feeling suddenly unwell.
Infections can become serious while white blood cell counts are low.

Does any of this apply?
Book an appointment
Arrange a medical assessment for bone pain, swelling, or a lump that persists, worsens, wakes you at night, or has no clear explanation.
A limp or reduced use of an arm or leg also deserves assessment, particularly when it does not improve.
Follow the team’s specific instructions rather than waiting for a routine appointment.
Routine questions about pain control, treatment effects, rehabilitation, or follow-up scans can usually be discussed with the cancer team during normal contact hours unless symptoms are rapidly worsening.
Every sign above is quoted from the sofidex article on Ewing sarcoma. If you are not sure, err upward — it is always reasonable to be checked.
