Had A Painful Lump On Occiptal Condyle, Swell And Radiate To Head. Can It Be Lymphoma?

Question : Hi. I had a painful lump on my right occiptal condyle for a couple weeks, would swell and radiate up the right side of my head. I went to Dr and the school I am attending and he thought it was a cyst and sent me home. I went back a week later and it still hurt so he made an appt for a cyst removal a week later. He removed the "cyst" and it sent it to pathology. A week later the pathologist called him and told him to re-examine me. The "cyst" was not a cyst but an infarcted lymph node. Because there was not enough viable tissue inside the lymph node the pathologist could not "rule out" lymphoma. No abnormal cells were found on the outside layer of the node. The school Dr took a chest xray, CBC, and LDH. The xray was normal, waiting for blood test. Is this enough? I feel the dr didn't do much but palpate lymph nodes and take xray. Did not examine me elsewhere take BP, look in ears/throat ect. I still have pain on the right side of head but he said its a kind of headache. I am worried and not satisfied. What to you advise?
