swollen lymph node

I have an enlarged non painful axilla lymph node and an enlarged tonsil on the same side. I have just had MRI of Tonsil and ultrasound of Lymph node and both came back normal. However I have sweats, breathing/recurring chest infections, fatigue, joint pains, constant runny nose and itchy feet. Blood tests normal.
If lymph node looks ok on ultrasound can Lymphoma be ruled out considering I have all these other symptoms?
Thanks
