Non-Hodgkin's Lymphoma Shoulder Pain: Causes, Symptoms, and Treatment
Shoulder pain can be one of the first warning signs of non-Hodgkin's lymphoma. Non-Hodgkin's lymphoma (NHL) is a cancer that starts in the lymphatic system, a network of lymph nodes and vessels that help fight infections.
In NHL, white blood cells called lymphocytes grow abnormally and accumulate in lymph nodes, causing them to swell. These swollen nodes can press on nerves, muscles, and surrounding tissues, leading to shoulder pain.
This article explores the links between NHL and shoulder discomfort. It covers possible causes, associated symptoms to watch for, and diagnosis and treatment options for lymphoma shoulder pain.
Causes of Non-Hodgkin's Lymphoma Shoulder Pain
There are several ways swollen lymph nodes from NHL can trigger shoulder pain:
Suprascapular Node Involvement
Lymph nodes above the shoulder blade can become enlarged. This compresses the suprascapular nerve, causing shoulder and upper arm pain.
Axillary and Cervical Node Swelling
Armpit and neck lymph nodes when enlarged can irritate nerves running to the shoulder joint, muscles, and skin.
Leukemic Manifestations
Certain fast-growing NHL subtypes release lymphoma cells into the bloodstream. These can infiltrate shoulder bones, leading to severe bone pain.
Invasion of Bones, Muscles, and Joints
In advanced NHL, lymphoma cells can directly invade bones, muscles, and tendons around the shoulder, causing inflammatory pain.
Referred Pain
Lymph nodes swelling near the diaphragm can cause "referred" shoulder pain. The diaphragm shares nerves with the shoulder region.
Symptoms Associated with NHL Shoulder Pain
Shoulder pain from NHL may occur alongside other lymphoma symptoms like:
Swollen Lymph Nodes
Enlarged, firm lymph nodes are a hallmark of NHL. They most often appear in the neck, armpit, or groin.
Night Sweats
Drenching night sweats where you soak your clothes and sheets can indicate NHL lymph node involvement.
Unexplained Fever
Fevers over 101F (38C) that have no clear origin may be an early lymphoma symptom.
Unexplained Weight Loss
Losing a significant amount of weight without dieting can signal NHL, especially in the elderly.
Fatigue
Excessive tiredness not relieved by rest that gets worse over time is a common lymphoma complaint.
Itchy Skin
Worsening itchy skin without a rash may result from NHL lymph node enlargement.
Chest Pain
Chest pain from enlarged mediastinal lymph nodes near the chest cavity.
Abdominal Pain
Stomach pain caused by swollen lymph nodes pressing on the intestines, liver, or spleen.
If shoulder pain occurs along with other NHL red flags, see an oncologist promptly for evaluation.
Types of Non-Hodgkin's Lymphoma Shoulder Pain
The quality and severity of shoulder discomfort can vary between NHL subtypes:
Dull, Aching Pain
Indolent or slow-growing NHLs like follicular lymphoma cause swollen but non-tender nodes. This leads to mild, dull shoulder aching.
Sharp, Shooting Pain
Aggressive NHLs like diffuse large B-cell lymphoma have rapidly enlarging, inflamed nodes that trigger sharp shoulder pain.
Bone Pain
Leukemic subtypes invading bones create severe shoulder bone pain, especially at night.
Pain With Movement
Swollen nodes near shoulder joint structures lead to shoulder pain when moving the arm.
Persistent Pain
Pain that varies but never fully goes away indicates persistent NHL lymphadenopathy (swollen nodes).
Tracking the pain qualities helps doctors pinpoint the possible NHL subtype and staging involved.
Diagnosing NHL Shoulder Pain
Doctors use a combination of approaches to diagnose NHL shoulder pain:
Medical History
Discussion of symptoms, onset, relieving/aggravating factors, and associated complaints.
Physical Exam
Feeling for enlarged or tender lymph nodes near the affected shoulder.
Imaging Tests
CT, PET, or MRI scans help visualize swollen nodes and assess sites of lymphoma involvement.
Biopsy
Removing parts of an enlarged lymph node for examination under a microscope.
Blood Tests
Complete blood count, LDH levels, and other blood work help confirm NHL diagnosis.
These diagnostic steps allow doctors to pinpoint the cause of shoulder discomfort and guide NHL treatment decisions.
Non-Hodgkin's Lymphoma Shoulder Pain Treatment
Treatment focuses on destroying lymphoma cells to shrink enlarged nodes pressing on shoulder structures. Options include:
Chemotherapy
Powerful IV drug cocktails to kill lymphoma cells throughout the body.
Radiation
High energy beams targeted at affected lymph node areas to destroy cancerous cells.
Immunotherapy
Medications boosting the body's own immune system to attack lymphoma cells.
Targeted Drug Therapy
Novel drugs blocking specific enzymes and proteins essential for NHL cell survival.
Stem Cell Transplant
Replacing a patient's diseased bone marrow cells with healthy stem cells to reconstitute the immune system.
Surgery
Rarely, surgically removing single enlarged lymph nodes compressing nerves or tissue.
These lymphoma treatments both alleviate shoulder pain and target the underlying NHL.
Questions to Ask Your Doctor
When meeting with your oncologist about NHL shoulder discomfort, consider asking:
- What lymph nodes are enlarged and likely causing my pain?
- What NHL subtype and stage is indicated by my symptoms?
- Will my pain improve with treatment of the lymphoma?
- Should I avoid certain shoulder movements?
- Are anti-inflammatories or pain medications appropriate?
- Could physical therapy help strengthen my shoulder?
Discussing questions and concerns ensures you understand your prognosis and treatment plan.
Coping with NHL Shoulder Pain
These self-care tips can help manage NHL shoulder discomfort:
- Apply cold or warm compresses to painful areas
- Avoid lifting heavy objects with the affected arm
- Take over-the-counter pain relievers as needed
- Sleep in a comfortable position using pillows for support
- Practice gentle shoulder stretches and exercises
- Reduce stress through relaxation techniques
Report any severely worsening pain or loss of shoulder function to your oncology team promptly.
Outlook for NHL Shoulder Pain
The prognosis for NHL shoulder pain depends on lymphoma subtype and response to treatment:
- Indolent NHL shoulder pain often gradually resolves with treatment
- Aggressive NHLs may improve more quickly with fast-acting chemo
- Refractory shoulder pain indicates poor response to initial treatment
- Relapsed shoulder pain after remission suggests lymphoma recurrence
Ongoing communication with your medical team is key for optimal shoulder pain management and NHL control.
Preventing NHL Shoulder Pain
While lymphoma cannot be prevented, maintaining a healthy lifestyle may lower risk:
- Avoid tobacco use and secondhand smoke
- Eat a balanced, whole food diet
- Exercise regularly
- Maintain a healthy body weight
- Control viral infections like HIV, EBV, and HTLV-1
- Use pesticides carefully to limit exposure
Genetic factors play a large role, but reducing environmental risk factors can aid prevention.
When to See a Doctor
Consult your doctor if shoulder pain arises alongside:
- Swollen lymph nodes lasting over 2-4 weeks
- Unexplained fever, drenching night sweats
- Sudden, unintentional weight loss
- Severe fatigue impacting your daily function
- Itchy skin or rashes
Prompt evaluation of shoulder discomfort with systemic NHL symptoms allows early diagnosis and treatment.
The Bottom Line
Shoulder pain can signal enlarged lymph nodes pressing on nerves and tissues due to underlying non-Hodgkin's lymphoma.
Pay attention to NHL red flag symptoms occurring along with shoulder discomfort. See an oncologist for appropriate diagnosis and treatment to both improve shoulder pain and target the lymphoma itself.
With appropriate care, NHL shoulder pain often gradually resolves as enlarged lymph nodes decrease in size with treatment.
