What can i do at home for swollen glands?

Lymph nodes: Which glands (lymph nodes) are you referring to? If you have swollen lymph nodes in the neck and a recent upper respiratory infection, that may be normal. If you have lymph nodes in other areas like the arm pit or groin or the ones in the neck that don't go away, you need to see a doctor for evaluation.

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.
