2.Enlarged lymph gland.
Cyst-are soft structure,you can press it very easily and are pain less.At times they can get enlarged due to pressure or friction.They may or may not have a black dot in center.
Enlarged lymph gland:When ever there is some infection in the surrounding area the lymph nodes in that are gets enlarged.This is a protective phenomenon of our body.With the treatment of infection this subsides.They are firm in consistency and may be painful on pressure.
