Bactrim (sulfamethoxazole and trimethoprim) turned one swollen lymph node into numerous ones. blood labs came back normal. going to get biopsy tomorrow. any suggestions?

Biopsy: A biopsy is very reasonable given your history. Many different types of biopsies are available. You could have an excisional biopsy where a surgeon removes a lymph node or an fna where a small number of cells are removed via a slender needle or you could have a core biopsy (uses much larger needle). As a pathologist i prefer to see an excisional biopsy or a core. Good luck. Let us know result.

Biopsy: Enlarged lymph nodes can be caused by many things. A trial of antibiotics is sometimes warranted to attempt to treat an underlying infection. If that doesn't help, obtaining a biopsy can be very helpful in ascertaining the cause. A pathologist will examine the biopsy and special tests can be run on the sample if need be to help determine cause. I hope you get an answer and feel better soon.
