Does multiple myeloma cause itching?
Itching (pruritus) isn’t a direct symptom of multiple myeloma, but some associated conditions can lead to itching. For instance, increased blood calcium levels (hypercalcemia) from bone breakdown can cause itching. Additionally, secondary conditions like kidney dysfunction or the development of amyloidosis (protein deposits) in multiple myeloma patients can manifest with itching. It’s also possible that some medications used for treatment can cause allergic reactions or skin side effects that include itching.
