I have had swollen lymphnodes for the past year or so. I noticed a large mass behind my ear about six months that was more in the posterior neck area. It was very hard and does not move and does not hurt unless messed with. All of the lymph nodes are painless! I went to the doctor because I kept gettting more swollen lymph nodes along the cervical chain of the posterior and anterior neck. The Dr. immediately mentioned possible lyphoma and said need to have a Ct-scan. The results of the scan are as described! Several lymphnodes along the cervical chain are enlarged on both left and right, the biggest lymphnode being 15.0 mm. There is a 2cm mucous retention cyst of the right maxillary sinus and mucous thickening of the left maxillary wall. The scan says numerous lymph glan enlargement. The results state from the Dr. that read the scan said he fills lymph node enlargement is due to inflammatory etiology. My question is, is it possible for a cyst in the sinus cavity and thickening of the nasal wall to cause such enlargement of the lymphnodes in the neck for this long of time? Any info would be greatly appreciated. My Dr. thinks this is my problem and thinks that a 30 day antibiotic along with nasal irrigation will fix the lymphnode problem even though they have been swollen and painless for over a year. What do you think? If anyone has experienced this problem please respond for I am scarred to death it is lymphoma.
