I am a 16-year-old female. In March 2014, I noticed a swollen lymph node in the right side of my neck. I didn t think much of it. This lymph node is still swollen, and I can still feel it. However, recently, I started having pain in my right groin area. I haven t been able to feel a swollen lymph node in the groin area, but I am worried that I may have a form of lymphoma. Is it abnormal for a lymph node in the neck to stay swollen, and is it just a coincidence that I have pain in my right groin area (where there are also lymph nodes?
