Probably concern: The rule of thumb for any antibiotic to work is 72 hours. In your case it's been less than that, however, the fact the disease is getting worse is a red flag. Bactrim (sulfamethoxazole and trimethoprim) may not be a right choice for a swollen lymph node. It is a good choice for a skin infection, but yours appears to be related to the lymph node. I'd call the prescribing physician and report your symptoms.
