My husband had a analogous stem cell transplant earlier this year Jan / February for kappa light chain myeloma. He recovered well and is apparently in remission. His kappa cells have recently started rising again in blood test and I'm wondering if its a sign of early relapse. He is on maintenance dose of 10 mg lenalidomide which last week was increased to 15 mg. Im feeling anxious about this. I am a nurse myself so maybe just overthinking things . I emailed the nurse coordinator today and asked her to check with the Dr but he hasn't replied to her. All other bloods are fine at thus stage. Protein a little low. Urea elevated slightly. I appreciate and thoughts on this. Should I be doing more .
