Waldenstrom's, CLL or MGUS?

@jlh1
Greetings, and welcome to Connect.
How frustrating when you get so many opinions about blood abnormalities. You don’t know what to worry about so I suspect you worry about all of them.
When I first read about MGUS online, it’s like reading an annual evaluation at work. My boss might say 20 really nice things about my performance but it’s that one area in which I need improvement that I obsess about.
It’s clear that you have to get a solid diagnostic workup to know what you are dealing with. My PCP was transparent with me that she knew very little about blood disorders. I appreciated her candor. She sent me to an oncologist/hematologist for a thorough diagnostic workup because I have the M paraprotein in my blood. She helped make the connection by making a referral to a trusted cancer treatment practice located close to me. They took it from there.
MGUS is not cancer, but as a MGUS patient, my health is monitored closely to ensure that my MGUS does not progress to Smoldering Multiple Myeloma or Multiple Myeloma. Statistically, the odds are in my favor that it will not progress in what is left of my lifetime, but if it does, the treatment response is very encouraging.
I would think that you would benefit from a good diagnostic workup that will give you a definitive diagnosis.
Here is some good information about MGUS. Don’t be discouraged, the right treatment provider is out there for you. If I were going to get hip replacement I would want to find the surgeon who does many hip replacements a week, rather than the gal or guy who did an ortho rotation ten years ago. You need to find the right specialist.
Did your bloodwork indicate the presence of the M paraprotein?
I’m glad you found us. We have a wealth of experience here among our members and I’m sure they will be helpful.

@jlh1 Welcome to Mayo clinic Connect. Surely that kind of "it could be this, but could be that" discussion will bring on many doubts!

As @pmm commented, some specialists may not have the experience or education to adequately monitor/diagnose your situation. Are you near a large teaching hospital or cancer center? I found this source that might be of help to you: https://www.medifind.com/specialty/hematology

Meanwhile, take a deep breath. Relax. Don't go down the "rabbit hole" of Dr. Google, which may be very tempting!

Hard to understand why your Doctor won't do a bone marrow biopsy. My oncologist wanted a second biopsy during a visit and just asked me if I had a few minutes and he did right there in about 20 minutes. Maybe you need a new doctor with the experience.
