three days ago i noticed a lump/or lymphnode under my left jaw pop up, it got larger the next day(yesterday) and today is the same size. I have never had anything like this, it doesnt hurt, i feel absolutely fine, i went to an M.D. and couldnt figure anything out, and gave me zathromax to take incase it was a problem. I have a littile disconfort going around the side to the back on my neck. I was curios what should i do go back and ask for a specialist or is it my body doing its own thing. thanks

There are many reasons a lymph node can swell or pop up. It doesn't always mean cancer, thank goodness. If you are not comfortable with your first MD visit I would go see a cancer MD and get checked out. It never hurts to be real sure. Take care and let us know what happens. God Bless
