Thank you for reading and please give me some advice if you can. Ive been having night sweats for a year, severe itching in my groin on the right hand side, fatigue and aching in my groin on the right. I've also been experiencing lower back pain. Blood tests are normal, had a chest x Ray which is normal, just got results of ultrasound on abdomen, liver and kidneys and they're normal. During my ultrasound they did an internal pelvic ultrasound which they said was normal also. Since my itching is in my right ground area I've been worried about the lymph nodes in that area. Would my groin lymph nodes have shown through these ultrasounds?

Im just not sure if they were checking for signs of lymphoma or not and am wondering what I should do next, what should I ask for if I want to rule out lymphoma? Or have they already done this. Thank you.
