Having Lower Back Pain. Fine Needle Biopsy Done. Found Swollen Lymph Node. Prognosis?
Welcome to XXXXXXX forum.
As you have previously mentioned that lymph nodes are painless; there appears to be least possibility of Cat scratch disease.
Cat scratch disease is caused by Bartonella henselae, a bacteria.
As it is infectious in nature, fever, back ache, tender lymphadenopathy may be presenting features.
There may be high chances of enlarged lymphadenopathy due to active Rheumatoid arthritis and Sjogren's syndrome.
You should consult with XXXXXXX medicine specialist/ rheumatologist and should go for detailed evaluation.
You must take low dose steroids along with disease modifying antirheumatic drugs.
Control of active rheumatoid arthritis may take time and you should take proper treatment for RA.
As such there is no need of treatment for suspected cat scratch disease. It is self remitting in nature.
In severe cases, doxycycline, azithromycin and ciprofloxacin may be helpful.
Hope that helps.
Let me know if I can address any more concerns.
Take care,
Dr. Mayank Bhargava
