Be seen today
Contact your haematology team promptly if you develop new or worsening bone pain, unusual tiredness, repeated infections, reduced urination, increasing thirst, or side effects that make it difficult to eat, drink, walk, or take medicines.
A fever, shaking chills, or sudden illness can require same-day assessment because treatment may lower infection-fighting white blood cells.
These symptoms can have causes other than myeloma, but they need urgent assessment.
