Hi and thanks for the query, Swollen lymph nodes and joint pain deserve a critical evaluation. they might be linked as well as not linked. Depending on the sequence of the evolution of the symptoms, knowing exactly what preceded the other could be a gateway in solving this confusion. Positive anti nuclear antibodies very suggestive of systemic lupus erythematosus or other autoimmune disease. this shall however require the opinion of a rheumatologist. Swollen lymph nodes could at times be observed in autoimmune conditions, but more severe conditions must be excluded first. Lymph node TB , lymphomas deserve a formal exclusion, through lymph node biospies, other blood tests and scans depending on the past history, clinical evaluation and appreciation of the internist. I therefore suggest you book an appointment with your internist and/ rheumatologist for a more detailed evaluation and appropriate management plan. thanks and best regards, Luchuo, MD.
