question: Noticed in bed last night that the left gland under my chin was swollen - only the left. It doesn t hurt except a slight tightness in swallowing. I do not have any other symptoms. It seems to have gone down a little by the time I woke up - but now it seems quite enlarged again - like a very soft egg. I think it responds to cold a little - when I put my cold hand that had just held a cold water bottle to the site it seemed to retract slightly.
