Hi, Thanks for posting in HCM. I understand your concern. Lymph node are part of immune system and help the body to fight against infection and disease. As lymphatic fluid travels through the body, immune cells in the lymph nodes trap bacteria, viruses, and other potentially harmful substances and destroy them to help prevent their spread. As you have stated that your grand daughter had one lymph node removed and she has around 7-8 enlarged lymph node around the removed lymph node. I must inform you that the most common reason for enlarged lymph node is bacterial infection, viral infection as well as skin, tooth and ear infection. You haven t mentioned the position of enlarged lymph node but other causes may include cancers and immune deficiency disorders. I am sure the removed lymph node would be sent for pathological examination and cause of enlarged lymph node would be known by the results. Treatment would depend on the cause of enlarged lymph node and simply treating the cause would reduce the size of lymph node. At home you can apply warm, wet washcloth to the area, you can also take over the counter pain relieving drugs and i would advice rest and healthy diet to recover from illness. Hope the information provided would be helpful. All the best.
