My left posterior triangle lymph node 5b measures 10.5mm x 4.2 mm is it normal ? I had pain and can feel it when touching but after taking antibiotics it has reduced in size and no pain but still i can feel it when i touch is it normal And is 4.2mm the short axis diameter of lymphnode ? Doctor say my lymphnode is reactive and enlarged I have chronic tonsils and bleeding gums my gums stopped bleeding after taking antibiotics I am very worried as google says it can be serious I had no fever or any other symptoms i am very anxious and cannot sleep at night Your reply will be appreciated
