Lump on neck and behind ear

[BenFranklin45]

prayers needed! This all started a year ago with just a little knot on the back of my neck to maybe having cancer! Started off as a knot on the back of my head right where necks start on the bottom of head.. then I noticed I had a tiny knot in my neck. Did some research and cancer started to pop up on the Internet.. I freaked out and anxiety went into overdrive.. doctor examined me and thought it was due to allergies.. got cat scan and the side with knot the lymph nodes and glands was bigger but they said they didn’t see anything wrong .. started to get headaches and ears was clogged up with some numbness in face.. doctor told me to take some Flonase . And said I might need anxiety meds.. he told me he would run blood test just to see if he found anything there.. he said everything was good.. and he really thought I was crazy.. after a while symptoms died down and now they have came back last month.. now I’m freaking out.. knot in my neck and behind my ear never gets big at all then goes away especially the one in my neck.. does this sound like cancer or could it really just be something else and anxiety? I been getting headaches just on the said on the side of my head like tension headaches which have me freaking out more now thinking I might have some kind of head or throat or salvia cancer.. I have a MRI Monday but I’m scared, because I don’t know what else it could be
