A member asked:
For what length of time do lymph nodes usually stay swollen with pneumonia?
3 doctors weighed in across 2 answers
A Few weeks: Lymph nodes do enlarge due to infections, but they would then settle down in 4-6 weeks after the infection has resolved. So you can watch them for a few weeks to check that they are regressing and not increasing in size.

Monitoring Centers: Lymphatic system absorbs/carries things too big to go into the arteries/veins like bacteria eaten by white cells and digested food. Lymph nodes "taste" the lymph for anything bad like bacteria/viruses/cancers, etc. When it detects a problem, it alerts the immune system and your body reacts. They enlarge in response to the inflammation they create when they react. They shrink when all is well.
