Multiple Myeloma
Hello, doctor.
Last month, after being diagnosed with COVID-19, I developed petechiae on my calves two weeks later.
I went to the hospital, and the physician said it was vasculitis induced by the immune response after the infection.
After taking steroids for a week, it improved.
I also underwent other blood tests and urinalysis.
The complete blood count showed WBC 6.7, RBC 5.35, MCV 88, MCHC 33.2, MCH 28.8, RDW 12.3, Platelets 303, PDW 12.1, MPV 10.4, Neutrophils 68, Lymphocytes 26, Monocytes 5.2, Eosinophils 0.4, Basophils 0.3, and Absolute Neutrophils 4569, all of which were normal.
ESR was 1, CRP was 1.31, AST was 17, ALT was 32, and Creatinine was 0.92, all normal as well.
The urinalysis was also normal.
Later, I tested C3, C4, A-DSDNA, ANA, RPR, IgA 158, Anti-ICSA, and Anti-BMZA, all of which were normal.
However, RF IgM was 13.9 (normal range 0-6), and Cryoglobulin was positive for IgM (1+).
I found that positive cryoglobulinemia is usually associated with hepatitis B/C, but I tested negative for both last year.
I also discovered that it might be related to multiple myeloma since I have recently been experiencing lower back pain and some pain in my left thigh and calf (though this symptom has occurred occasionally in the past; an X-ray showed some lumbar degeneration).
Additionally, a long time ago, an MRI of my cervical spine revealed nerve compression due to a herniated disc, causing pain when turning my neck to the left, and sometimes my arm would hurt as well.
I underwent physical therapy, which helped significantly, but I have noticed discomfort returning in recent months.
Therefore, I am concerned and would like to ask the doctor if there is a possibility that I might have multiple myeloma.

Guang, 43 years old, male.
Please forgive me, as I am not a hematology specialist.
I recommend that you see a hematologist for blood tests.
Wishing you good health.

Based on your detailed description of symptoms and medical history, it is understandable that you are concerned about the possibility of multiple myeloma, especially after experiencing various health issues following your COVID-19 infection. However, let's break down your situation and clarify some important points regarding multiple myeloma and your symptoms.
Multiple myeloma is a type of blood cancer that affects plasma cells, which are a type of white blood cell responsible for producing antibodies. The disease can lead to a variety of symptoms, including bone pain, anemia, kidney dysfunction, and increased susceptibility to infections. Common laboratory findings in multiple myeloma include elevated levels of monoclonal proteins in the blood or urine, anemia, elevated calcium levels, and renal impairment.
From the laboratory results you provided, it appears that most of your blood work is within normal limits. Your complete blood count (CBC) shows normal white blood cell (WBC) and red blood cell (RBC) counts, which is a positive sign. The normal levels of creatinine, AST, and ALT suggest that your kidney and liver functions are stable. Additionally, your ESR (erythrocyte sedimentation rate) and CRP (C-reactive protein) levels are also within normal ranges, indicating that there is no significant inflammation or infection at the moment.
The presence of cryoglobulinemia (positive IgM) can be associated with various conditions, including infections, autoimmune diseases, and certain malignancies, but it is not specific to multiple myeloma. It is important to note that cryoglobulinemia can occur in response to infections, including viral infections like hepatitis, but it can also be a transient condition following an immune response to infections such as COVID-19.
Your symptoms of back pain and leg discomfort could be attributed to several factors, including pre-existing conditions like degenerative disc disease or muscle strain, especially if you have a history of spinal issues. The pain you are experiencing may not necessarily indicate multiple myeloma, particularly since these symptoms have been present intermittently in the past.
Given your concerns about multiple myeloma, it is essential to consider the following:
1. Consultation with a Hematologist: If you are still worried about the possibility of multiple myeloma, it would be prudent to consult a hematologist. They can perform additional tests, such as serum protein electrophoresis, immunofixation electrophoresis, and possibly a bone marrow biopsy if indicated, to assess for the presence of abnormal plasma cells.
2. Monitoring Symptoms: Keep track of any new or worsening symptoms, such as persistent bone pain, fatigue, or any signs of infection. If you experience significant changes, it is crucial to seek medical attention promptly.
3. Follow-Up on Cryoglobulinemia: Since you have a positive cryoglobulin test, it may be beneficial to follow up on this with your healthcare provider. They can help determine the underlying cause and whether any further evaluation or treatment is necessary.
4. Managing Pain and Discomfort: For your current symptoms of back and leg pain, consider discussing pain management strategies with your healthcare provider. Physical therapy, pain medications, or lifestyle modifications may help alleviate discomfort.
In conclusion, while your symptoms and laboratory findings warrant careful consideration, the current evidence does not strongly indicate multiple myeloma. It is essential to maintain open communication with your healthcare providers and pursue further evaluation if necessary. Your health and well-being are paramount, and addressing your concerns with a specialist will provide you with the best guidance moving forward.
