8 days ago I came home from work and from when I got out of the car to the house a red hard lump appeared on my neck under my ear lobe. The lump went down, but tenderness under my jaw and in my neck soon came along with a lot of post nasal drip, but barely any congestion in my nose. The doctor told me that it was probably just a cold and advised me that she felt no lymph node swelling.  The next morning, I woke up and I felt better. My husband checked my neck for me to make sure the swelling was still down. 20 minutes later I went into the bathroom and there was the red hard lump again in the same spot. Looks very much like a mosquito bite, but without itching or pain that always accompanies bites Ive gotten all my life. That was 2 days ago. The post nasal drip has continued and now I have a sore throat from the post nasal drip. Negative for flu. Negative for strep. I also had a full blood work up done in a hospital 30 days ago and no problems were noticed.
Hi, dairy have gone through your question. I can understand your concern. You have sore throat, post nasal Chat Doctor.  You may have upper respiratory tract infection. Your lump may be reactive lymph node or mosquito bite. You should take a course of antibiotics like azithromycin, amoxiclav, levofloxacin or cephalosporin. You should also take antihistamines
