Hi. I have a hard,immobile, pea sized lump behind my left ear that I noticed about 4 days ago the night after my husband rubbed my neck. It was sore the next day and is now sore on and off. I was seen by my doctor today and she said it was a lymph node. She said I could either wait a few weeks to see if it goes away or that I could have an ultrasound on it because she knows how worried I am about it. She also said I had some fluid behind the ears and my sinuses were very swollen. She said it wasn t too concerning, but the fact that it is so hard and immobile really freaks me out. She prescribed an antibiotic and flonase. Can t stop worrying about it. What are your thoughts. Need some piece of mind. Thanks, Christie
