I am a teenage girl, I am super worried I have lymphoma. I have had 3 swollen lymph nodes in my neck for about 5 months. Then about 3 months ago I found another 3 in my groin. 1 week ago I found one in my armpit and 3 days ago another in the other armpit. I have had a blood test 3 months ago I think it was, due for another two. I have low hemoglobin causing shortness of breath. I've also had extreme dizziness and nausea for a while now. Also, my rib cage on the left hand side is noticeably sticking out further than the left, but I don't have scoliosis. Can someone help me?
