There are many lymph
nodes in our body and they can get inflammed due to some sort of infection
like tuberculosis;boils;infection of any part.Also few lymph nodes are palpable in slim people and they are mainly felt in neck
region so that may be a gilti you are feeling.The difference between the normal and infection related gilti is the gilti due to infection will be painful and may increase in size the normal one will be painless and remain as it is so if the gilti is painless no reason to worry.
