Can weakness and enlarged lymph nodes cause elevated WBC count?

Welcome to icliniq.com.

I have read your query, and I can understand your concern.

Your main complaint was recurrent swollen lymph nodes in the neck and weakness. However, your WBC (white blood cell) counts in the first report were mildly elevated, and there was no alarming rise. At present, your WBC count is within limits. According to clinical correlation HIV (human immunodeficiency virus), autoimmune connective tissue problems, thyroid issues, and mononucleosis must be ruled out. I would suggest the investigation is needed with peripheral blood smear examination, ELISA (enzyme-linked immunosorbent assay) testing for HIV, antibody testing for mononucleosis, serum TSH (thyroid stimulating hormone), T4 estimation (thyroxine test), ANA estimation (antinuclear antibody), rheumatoid factor estimation, and autoimmune disease cell panel. If a specific cause is found, then they are treated accordingly. When lymph node swelling occurs it is better to take FNAC (fine needle aspiration cytology) from that lesion to rule out the nature of the lesion, whether it is a benign, malignant tumor, or infective lesion. Additional investigation with CRP (C-reactive protein) is also recommended. Your liver, spleen, and general lymph nodes also should be palpated. If no specific cause is found, then weakness might be from fibromyalgia. As far as the CBC (complete blood count) report is concerned, it is not very alarming in my opinion. Consult a physician or hematologist for examination and accordingly do further work up as per need.

I hope my answer will help you.

Thank you.
