Smoldering Multiple Myeloma and symptoms

Posted by maddogstormy @maddogstormy, May 21, 2025

I have had MGUS since 2021 and now have smoldering multiple myeloma. I am now feeling something new. A symptom. Like a twinging or dull aching pretty much everywhere. I am wondering if this is a bone symptom and if there any descriptions of bone pain. I have my next follow up in a week and I am concerned that I will be told I am active and have elevated to multiple myeloma.
Thanks.

Hi again.
I received my last dose of linvoseltamab on June 2nd in a trial at Dana-Farber for smoldering multiple myeloma. IVIG (Privigen) infusions are scheduled every four weeks, and I’m now starting recovery now day 32.
This medication affects everyone differently, and my experience is just one. It took my M-spike and free light chains out of detectable range. It also had an enormous off-target impact on much of my immune system ie my IgA and IgM are both negligible. I tried to keep working in person until I got too sick from common colds and respiratory infections.
One thing I’d flag for others: I wish they had started the IVIG infusions four weeks earlier than they did. Insurance was challenging and mine were delayed about five weeks. If you’re going into this, it may be worth asking about immunoglobulin support early.
I would not change my decision to participate. I can see a longer horizon than I could a year ago, when I could barely walk.
I’m finding recovery to be a complicated and delicate process, progress and regress, sometimes in the same day. The intense fatigue arrives randomly and can be hard. I’m also blessed with a loving family and community, and I do my best to stay connected as I move through these changes.
Thank you all for this space to share a bit of my story. I’m inspired by you.

Good morning.
I am now past cycle 1 and have had two monthly doses and there are three remaining. So much to share and consider. I do have a question for folks. How have you handled deeply suppressed iga and igm immunoglobulins? I am receiving Privigen IV infusions to support IGg and that is a big help. From my understanding the iga and igm are my front line defense against Respiratory viral and bacterial infections. I am concerned and have really limited my exposure to public spaces and gatherings and I also know isolation is not helpful either.
Many thanks.

I am also enrolled in the Dana Farber clinical trial 24-135. Just received my second step up dose of Linvoseltamab 4 mg along with the steroid and antihistamine.

I have intermediate SMM with gain 1q and monosomy 13. IGG Lambda. M-spike 1.8 and flc ratio of 30.1. Plasma cell percentage 10-15%.

Randomized into 200 mg track. One more step up dose, 25 mg, next week before my first full dose, 200 mg, on 8/10.

Just curious, what did you find most challenging about your experience.

My SMM was caught by my rheumatologist as I was being evaluated for PMR. He was very thorough in my blood work and noticed markers that pointed to a blood disorder in addition to a PMR diagnosis. He referred me to his friend's hematology-oncology practice so I could be seen quickly. My PET scan came back clean but my bone marrow biopsy put me in the low to intermediate SMM range. Unfortunately, I was on 25mg prednisone for PMR when both tests were performed and it's not possible to know the amount of suppression that caused. I'm down to 5mg prednisone now and have new blood work scheduled for August 4. I'm 73 with osteoarthritis and PMR, so I don't know if I have any SMM symptoms. My rheumatologist thinks that SMM is causing shoulder pain because 25mg prednisone relieved all PMR pain except for my shoulders.

Did you have side affects from the IVIG? How long do you have to be on a drip?
My multiple myeloma is stable and I take a monthly chemo to maintain my condition. However my immune system is severely compromised and the doctor has suggested IVIG if I start getting a lot of infections.

I was introduced to multiple myeloma (MM) when my 53 year old daughter was diagnosed with full-blown MM. I, at 79, was diagnosed with MGUS about 7 months later, after taking blood tests for what I thought might be neuropathy, knowing that my daughter had similar symptoms.
To make a two year story shorter, by the time my daughter was diagnosed she was experiencing extra medullary effects of myeloma, had a compression fracture of her vertebrae and bone lesions throughout her body. It was the compression fracture that got her attention. It was fortuitous that she and her family had moved to within 50 miles of the Jacksonville Mayo Clinic 6 months prior, and so they treated her for two years, during which time she went through 9 lines of treatment, each one becoming refractory, including T cell transplant. She had been diagnosed as triple risk, meaning she had three of nine risk-markers. So the prognosis was never good, but she fought valiantly for those two years. There were many lessons learned along the way, and we - her parents – were lucky to spend about a third of our time with her during this period.
As indicated above, I was diagnosed with MGUS, igA, Kappa, and put on a schedule of visiting an oncologist every 4 months. Within a year I had had a pet scan, mri, skeletal x-ray scan, and a bone marrow biopsy. Unlike my daughter, I had no risk markers identified. As my numbers slowly progressed – in just 18 months - I got pushed into the smoldering myeloma category, primarily because bone marrow showed a greater than 20% occurrence of myeloma. However CRAB criteria have not been fulfilled yet. I am about to have my second pet scan.
What is curious to me and should pertain to the larger myeloma community: What is the progression of myeloma? Does everyone start at MGUS, and then proceed to smoldering, and then (maybe) to multiple myeloma? It’s a hard question because you do not feel the symptoms until something like a bone breaks, or extra-medullary shows up. Or you just luckily have a blood test which alerts you to the possibility. So, did my daughter have MGUS and SMM for years before her diagnosis? The fact that once we discovered it, it was virulent and very aggressive and her numbers would peak very quickly when she went refractory, I think probably speaks to her high-risk category. So, I would think that there are different rates for the progression, but I also think that for everyone there is a progression; i.e. - you don’t just start out with multiple myeloma. And this speaks to the needs that have been expressed in many of these postings that we need a method for identifying the beginnings of myeloma much earlier in the process, when we might therefore have the opportunity to slow it down before it does a lot of damage.
In my personal case, I’m very analytical and have trend plots for all my myeloma numbers; they are slowly creeping upward. What would be great to find out is if there are any data that guesstimates prognoses based on the number of risk factors one has.

Hi, regarding your daughter's compression fracture of her vertebrae, do the doctors believe that the fracture is directly related to her MM? I was recently diagnosed with MGUS after the osteoporosis in my spine suddenly deteriorated to the severe level. I haven't fractured yet; I'm on treatment for this. However, the oncologist said the severe osteoporosis isn't due to MGUS. I'm just curious...when is osteoporosis directly related to MGUS or MM and when isn't it?

@sb428 When I hear "if you start getting a lot of infections" I think about someone who said "that's like promising to get you a car with brakes after you've been a couple of car wrecks when they know you live in the mountains."

Hi. Congratulations on beginning your treatment. For me the treatment hit my immune system harder than I expected. It helped a lot when I was given IVIG infusions which will continue until my immune system begins to function.
Fatigue was and continues to be significant.
I am finally designated CR. My bone marrow biopsy last week results are not yet complete. Although it is clear I am not yet MRD Negative.
I am describing this stage as a kind of recovery. It’s different and unfamiliar territory for me. I am shocked at how short this has been and how long it feels.
I would say I am not even sure how to talk about it or make sense of this yet.
I do think and I might even feel like I am getting better.
I hope that is helpful. I am sure every person who receives this treatment will have a different experience.
I also know that the whole team at Dana Farber is amazing. I am fortunate to be there.

Thank you that’s good. So you’re a Jayhawk fan! I had no real side effects from Ivig infusions except a headache a couple of times.

I could not do this without the Ivig infusions. Less than 90 minutes to receive. Good luck with your recovery.
