I recently noticed a swollen lump in the right side of my neck about 2 inches below my ear. Saw a doctor, she said it was probably due to some infection...gave me antibiotics and said take these and see if it goes away. I have no symptoms of any infection. It's been 2 weeks and the lump is still there. I only have two other issues...one I salivate A LOT. 2...I am having a terrible problem with facial flushing. Any ideas on what it could be?
